74HCT373DB,112

Latches Overview

The 74HCT373DB,112 is an octal D-type transparent latch featuring three-state outputs manufactured by Nexperia. It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes the 74HCT logic family for TTL-compatible input levels. The device provides eight independent latches with a common latch enable (LE) and output enable (OE) control. It supports data storage during LE low states and high-impedance output states when OE is active. The component is housed in a 20-SOIC surface-mount package.

Latches Feature Summary

• Octal D-type transparent latch architecture with three-state outputs
