M74HC533TTR

Latches Overview

The M74HC533TTR is a high-speed CMOS D-type transparent latch manufactured by STMicroelectronics. It features eight independent latches with tri-state outputs, housed in a 20-SOIC surface-mount package. The device operates within a supply voltage range of 2V to 6V and supports an operating temperature from -55°C to 125°C. Key electrical characteristics include a propagation delay of 12ns and output currents of 7.8mA for both high and low states.

Latches Feature Summary
