The Output Enable input does not affect the state of the latches, but when Output Enable is high, all device outputs are forced to the high-impedance state. Thus, data may be latched even when the outputs are not enabled. The 74HC373 is identical in function to the HC573 which has the data inputs on the opposite side of the package from the outputs to facilitate PC board layout. The 74HC373 is the non-inverting version of the HC533.
Features:
Output Drive Capability: 15 LSTTL Loads
Outputs Directly Interface to CMOS, NMOS and TTL
Operating Voltage Range: 2.0 to 6.0 V
Low Input Current: 1.0 mA
High Noise Immunity Characteristic of CMOS Devices
Chip Complexity: 186 FETs or 46.5 Equivalent Gates
20 pin DIP. Actual brand may vary from picture.

G4820A - 74HC373 Octal Non-Inverting Transparent Latch
Detailed Description
The 74HC373 is identical in pinout to the LS373. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. These latches appear transparent to data (i.e., the outputs change asynchronously) when Latch Enable is high. When Latch Enable goes low, data meeting the setup and hold time becomes latched.The Output Enable input does not affect the state of the latches, but when Output Enable is high, all device outputs are forced to the high-impedance state. Thus, data may be latched even when the outputs are not enabled. The 74HC373 is identical in function to the HC573 which has the data inputs on the opposite side of the package from the outputs to facilitate PC board layout. The 74HC373 is the non-inverting version of the HC533.
