Description

The SN54AHC373 devices are octal transparent D-type latches designed for 2-V to 5.5-V VCC operation.When the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is low, the Q outputs of SN54AHC373 are latched at the logic levels of the D inputs.

A buffered output-enable (OE) input of SN54AHC373 can be used to place the eight outputs in either a normal logic state (high or low) or the high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and increased drive of SN54AHC373 provide the capability to drive bus lines without interface or pullup components.
