The 74HC373 is a high-speed CMOS OCTAL LATCH with 3-STATE OUTPUT fabricated with silicon gate C2MOS technology. It achieves high-speed operation comparable to LSTTL while keeping CMOS low power dissipation.
A latch enables input (LE) and output enables input (OE) to control these 8-bit D-type latch es (OE). The eight outputs have a high impedance state when the OE input is high. Static discharge and transient excess voltage safety circuits are installed on all inputs.

The difference between 373 and 573 is only in the pin order. 74HC and 74LS have different logic thresholds; the exact CMOS equivalent to 74LS is the 74HCT series. In many cases, the difference doesn't matter, but it depends on your circuit.
There are several main differences:
Output: 74HC373 output is three-state output (OE control), 74HC377 output has only two states, either 0 or 1. The result of this difference is that 74HC373 can be applied to certain situations where multiple drive sources are jointly controlled (such as data buses). And 74HC377 can't.
Input: The input of 74HC373 is controlled by LE (high effective). The input of 74HC377 is not only controlled by LE (active low), but also controlled by CP (rising edge). The 74HC373 is suitable for latch ing data with levels, and 74HC377 is suitable for latch ing data with clocks. 74HC373 is more suitable for asynchronous applications, and 74HC377 is suitable for synchronous applications.
The function is to latch the data (or signal), the application is different, and the control method is also different.
