74LCX573MSAX

Latches Overview

The onsemi 74LCX573MSAX is an octal transparent latch integrated circuit belonging to the 74LCX logic family. It features a single 8-bit D-type latch with three-state outputs, designed for low-voltage operation between 2V and 3.6V. The device utilizes a 20-SSOP surface-mount package and operates within a temperature range of -40°C to +85°C. Key electrical characteristics include a maximum propagation delay of 9ns at 2.7V and 8ns at 3.6V, with output drive capabilities of 24mA high and low. Static current consumption is specified at 10µA.
