74ALVC1637DTR

Latches Overview

The onsemi 74ALVC1637DTR is a dual 8-bit transparent latch with 3-state outputs, part of the 74ALVC logic family. It operates within a supply voltage range of 2.7V to 3.6V and features low input capacitance of 6pF. The device provides high-speed performance with a maximum propagation delay of 3.5ns at 3.3V and 50pF load. It supports output drive currents of 24mA for both high and low states. Packaged in a 48-TSSOP surface-mount format, it functions reliably across an operating temperature range of -40°C to +85°C.
