MC74HC373ADWG

The MC74HC373ADWG from ON Semiconductor is a high-performance silicon-gate CMOS octal 3-state non-inverting transparent latch. This device features eight transparent D-type latches that follow the data inputs when the latch enable is high. When the latch enable goes low, the data meeting setup and hold time requirements becomes latched.

The latch enable input does not affect the state of the latches, but the output enable input forces all outputs to a high-impedance state when high. This allows data to be latched even when outputs are not enabled. The MC74HC373A is identical in function to the HC573A but with data inputs on the opposite side of the package for easier PC board layout.

Key electrical specifications include an operating voltage range of 2.0V to 6.0V for the HC variant, with a low input current of 1.0 μA. The output drive capability is rated at 15 LSTTL loads, and outputs directly interface to CMOS, NMOS, and TTL logic. The device operates across a wide temperature range from -55°C to 125°C.

Packaged in a 20-SOIC (0.295", 7.50mm Width) surface mount package, the MC74HC373ADWG is suitable for various digital logic applications requiring transparent latching functionality.
