SEMICONDUCTOR TECHNICAL DATA
Octal 3-State Noninverting Transparent Latch with LSTTL-Compatible Inputs
High-Performance Silicon-Gate CMOS
The MC54/74HCT373A may be used as a level converter for interfacing TTL or NMOS outputs to High-Speed CMOS inputs. The HCT373A is identical in pinout to the LS373. The eight latches of the HCT373A are transparent D-type latches. While the Latch Enable is high the Q outputs follow the Data Inputs. When Latch Enable is taken low, data meeting the setup and hold times becomes latched. The Output Enable does not affect the state of the latch, but when Output Enable is high, all outputs are forced to the high-impedance state. Thus, data may be latched even when the outputs are not enabled. The HCT373A is identical in function to the HCT573A, which has the input pins on the opposite side of the package from the output pins. This device is similar in function to the HCT533A, which has inverting outputs. * * * * * * 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: 196 FETs or 49 Equivalent Gates LOGIC DIAGRAM

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.
