74HC373; 74HCT373

Octal D-type transparent latch; 3-state

Rev. 8 — 6 September 2021

Product data sheet

1. General description

The 74HC373; 74HCT373 is an octal D-type transparent latch with 3-state outputs. The device

features latch enable (LE) and output enable (OE) inputs. When LE is HIGH, data at the inputs

enter the latches. In this condition the latches are transparent, a latch output will change each time

its corresponding D-input changes. When LE is LOW the latches store the information that was

present at the inputs a set-up time preceding the HIGH-to-LOW transition of LE. A HIGH on OE

causes the outputs to assume a high-impedance OFF-state. Operation of the OE input does not

affect the state of the latches. Inputs include clamp diodes. This enables the use of current limiting

resistors to interface inputs to voltages in excess of V_CC

2. Features and benefits
