74AHC373; 74AHCT373
General description
The 74AHC/AHCT373 are high-speed Si-gate CMOS devices and are pin compatible with Low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74AHC/AHCT373 are octal D-type transparent latches featuring separate D-type inputs for each latch and 3-state outputs for bus oriented applications. A Latch Enable (LE) input and an Output Enable (OE) input are common to all latches.
The ?373? consists of eight D-type transparent latches with 3-state true outputs. When LE is HIGH, data at the Dn inputs enters the latches. In this condition the latches are transparent, i.e. a latch output will change state each time its corresponding D-input changes.
When LE is LOW the latches store the information that was present at the D-inputs a set-up time preceding the HIGH-to-LOW transition of LE. When OE is LOW, the contents of the 8 latches are available at the outputs. When OE is HIGH, the outputs go to the high-impedance OFF-state. Operation of the OE input does not affect the state of the latches.
The ?373? is functionally identical to the ?533?, ?563? and ?573?, but the ?533? and ?563? have inverted outputs and the ?563? and ?573? have a different pin arrangement.
