Overview
The SN74LVTH373PWRE4 is a 3.3-V ABT (Advanced BiCMOS Technology) octal transparent D-type latch with 3-state outputs, manufactured by Texas Instruments. This component is designed for low-voltage operation, specifically at 3.3 V, but it also supports mixed-mode signal operation with 5-V input and output voltages. The latch enables data to be latched at the logic levels set up at the D inputs when the latch-enable (LE) input is taken low, and it features a buffered output-enable (OE) input to control the output states.
