| MOTOROLA SEMICONDUCTOR TECHNICAL DATA Octal 3-State Noninverting Bus Transceiver with LSTTL Compatible Inputs High-Performance Silicon-Gate CMOS The MC54/74HCT245A is identical in pinout to the LS245. This device may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The MC54/74HCT245A is a 3-state noninverting transceiver that is used for 2-way asynchronous communication between data buses. The device has an active-low Output Enable pin, which is used to place the I/O ports into high-impedance states. The Direction control determines whether data flows from A to B or from B to A. * * * * * * Output Drive Capability: 15 LSTTL Loads TTL/NMOS Compatible Input Levels Outputs Directly Interface to CMOS, NMOS and TTL Operating Voltage Range: 4.5 to 5.5 V Low Input Current: 1.0 A In Compliance with the Requirements Defined by JEDEC Standard No. 7A * Chip Complexity: 304 FETs or 76 Equivalent Gates LOGIC DIAGRAM A1 A2 A3 A DATA PORT A4 A5 A6 A7 A8 DIRECTION OUTPUT ENABLE 2 3 4 5 6 7 8 9 1 19 18 17 16 15 14 13 12 11 B1 B2 B3 B4 B5 B6 B7 B8 B DATA PORT MC54/74HCT245A J SUFFIX CERAMIC PACKAGE CASE 732-03 1 20 20 1 20 1 N SUFFIX PLASTIC PACKAGE CASE 738-03 DW SUFFIX SOIC PACKAGE CASE 751D-04 SD SUFFIX SSOP PACKAGE CASE 940C-03 DT SUFFIX TSSOP PACKAGE CASE 948E-02 20 1 20 1 ORDERING INFORMATION Ceramic MC54HCTXXXAJ Plastic MC74HCTXXXAN SOIC MC74HCTXXXADW SSOP MC74HCTXXXASD TSSOP MC74HCTXXXADT PIN ASSIGNMENT DIRECTION A1 A2 A3 A4 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 VCC OUTPUT ENABLE B1 B2 B3 B4 B5 B6 B7 B8 PIN 20 = VCC PIN 10 = GND A5 A6 A7 A8 GND IIIIIIIIIIIII II III I I IIIIIIIIIIIII II III I II IIIIIIIIIIIII IIIIIIIIIII IIIIIIIIIIIII II IIIIIIIIIIIII IIIIIIIIIIIII IIIIIIIIIII III I II II I I IIIIIIIIIII IIIIIIIIIIIII II I IIIIIIIIIIIII IIIIIIIIII Design Criteria Value Units Internal Gate Count* 76III ea ns Internal Gate Propagation Delay Internal Gate Power Dissipation Speed Power Product 1.0 5.0 W pJ 0.005 * Equivalent to a two-input NAND gate. 2/97 FUNCTION TABLE Control Inputs Output Enable L L H X = Don't Care Direction L H X Operation O i Data Transmitted from Bus B to Bus A Data Transmitted from Bus A to Bus B Buses Isolated (High-Impedance State) (c) Motorola, Inc. 1997 3-1 REV 7 MC54/74HCT245A II I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I II I I I I I III I I I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I IIIIIIIII IIIIIIIIIIII I I II I I I II I I I II I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I III I I I II I II I I I II I I I I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I II I I I II I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIII IIIIIIIIIIII I I II I I I II I I II I I I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I III I I I IIIIIIIII I I I I II I I I II I I I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I IIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII II I III I I II I I I I II I I II IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII II I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIIIIIIII II I I III I I IIIIIIIIIIIIIIIIIIIIIII III I III I I II I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I I IIIIIIIIIIIIIIIIIIIIIII III II I IIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIII I I II I I I I I I I IIIIIIIIIIIIIIIIIIIIIII II IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIII I I III I I I I I II IIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII I III I I I IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII IIIIII I I IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIII I IIIIIIIIIIIIIIIIIIIIIII MAXIMUM RATINGS* Symbol VCC Vin Parameter Value Unit V V V DC Supply Voltage (Referenced to GND) DC Input Voltage (Referenced to GND) - 0.5 to + 7.0 - 0.5 to VCC + 0.5 - 0.5 to VCC + 0.5 20 35 75 750 500 450 Vout Iin DC Output Voltage (Referenced to GND) DC Input Current, per Pin mA mA mA Iout DC Output Current, per Pin ICC PD DC Supply Current, VCC and GND Pins Power Dissipation in Still Air, Plastic or Ceramic DIP SOIC Package SSOP or TSSOP Package Storage Temperature mW Tstg TL - 65 to + 150 260 300 This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, Vin and Vout should be constrained to the range GND (Vin or Vout) VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open. v v _C _C Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP, SOIC, SSOP or TSSOP Package) (Ceramic DIP) * Maximum Ratings are those values beyond which damage to the device may occur.
