All inputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage. All floating bus terminals during High Z State don't need external pull-up or pull-down resistor. Figure 1: Logic Diagram DESCRIPTION The 74VCXHQ163245 is a dual supply low voltage CMOS 16-BIT BUS TRANSCEIVER fabricated with sub-micron silicon gate and five-layer metal wiring C2MOS technology. Designed for use as an interface between a 3.3V bus and a 2.5V or 1.8V bus in a mixed 3.3V/ 1.8V,3.3V/2.5V and 2.5V/1.8V supply systems, it achieves high speed operation while maintaining the CMOS low power dissipation and limited rise and fall time (Low EMI). This IC is intended for two-way asynchronous communication between data buses and the direction of data transmission is determined by nDIR inputs. The enable inputs nG can be used to disable the device so that the buses are effectively January 2005 n = 1, 2 Rev. 3 1/17 74VCXHQ163245 Figure 2: Input And Output Equivalent Circuit Table 2: Pin Description TFBGA54 PIN N A3 J3 A6, B5, B6, C5, C6, D5, D6, E5 E6, F5, F6, G5, G6, H5, H6, J6 A1, B2, B1, C2, C1, D2, D1, E2 E1, F2, F1, G2, G1, H2, H1, J1 J4 A4 D3, D4, E3, E4, F3, F4 A2, A5, B3, B4, H3, H4, J2, J5 C4, G4 C3, G3 TFBGA42 PIN N B3 F3 A4, A5, A6, B5, B6, C5, C6, D5 D6, E5, E6, F5, F6,G4, G5, G6 A3, A2, A1, B2, B1, C2, C1, D2 D1, E2, E1, F2, F1,G3, G2, G1 F4 B4 C3, C4, E3, E4 D4 D3 TSSOP PIN N 1 24 47, 46, 44, 43, 41, 40, 38, 37 36, 35, 33, 32, 30, 29, 27, 26 2, 3, 5, 6, 8, 9, 11, 12 13, 14, 16, 17, 19, 20, 22, 23 25 48 4, 10, 15, 21, 28, 34, 39, 45 42, 31 7, 18 SYMBOL 1DIR 2DIR 1A1 to 1A8 2A1 to 2A8 1B1 to 1B8 2B1 to 2B8 2G 1G GND NC VCCA VCCB NAME AND FUNCTION Directional Controls Directional Controls Data Inputs/Outputs Data Inputs/Outputs Data Inputs/Outputs Data Inputs/Outputs Output Enable Inputs Output Enable Inputs Ground (0V) No Connected Positive Supply Voltage Positive Supply Voltage 2/17 74VCXHQ163245 Figure 3: Pin Connection (top view for TSSOP, top through view for BGA) TSSOP TFBGA TFBGA Table 3: Truth Table INPUTS G L L H X=Don't care; Z=High Impedance FUNCTION OUTPUT DIR L H X A BUS OUTPUT INPUT Z B BUS INPUT OUTPUT Z A=B B=A Z 3/17 74VCXHQ163245 Table 4: Absolute Maximum Ratings Symbol VCCA VCCB VI VI/OA VI/OB VI/OA VI/OB IIK IOK IOA IOB ICCA ICCB Pd Tstg TL Supply Voltage Supply Voltage DC Input Voltage DC I/O Voltage (Output disabled) DC I/O Voltage (Output disabled) DC I/O Voltage DC I/O Voltage DC Input Diode Current DC Output Diode Current DC Output Current DC Output Current DC VCC or Ground Current DC VCC or Ground Current Power Dissipation Storage Temperature Lead Temperature (10 sec) Parameter Value -0.5 to +4.6 -0.5 to +VCCA+0.5 -0.5 to +4.6 -0.5 to +4.6 -0.5 to +4.6 -0.5 to VCCA + 0.5 -0.5 to VCCB + 0.5 - 20 - 50 50 50 100 100 400 -65 to +150 260 Unit V V V V V V V mA mA mA mA mA mA mW C C Absolute Maximum Ratings are those value beyond which damage to the device may occur.
