Part Number : 74HC373
Function : 3-state Octal D-type transparent latch
Package : DIP, SO, TSSOP DHVQFN 20 Type
Manufacturers : NXP Semiconductors.
The 74HC373, 74HCT373 is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL. It is specified in compliance with JEDEC standard no. 7A.
The device is an octal D-type transparent latch 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 devices 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 OEis LOW, the contents of the 8 latches are available at the outputs. When OEis HIGH, the outputs go to the high-impedance OFF-state. Operation of the OEinput does not affect the state of the latches.
1. 3-state non-inverting outputs for bus oriented applications
2. Common 3-state output enable input
