MM74HC573SJ

The MM74HC573SJ from On Semiconductor is a high-speed octal D-type latch designed using advanced silicon-gate P-well CMOS technology. It offers the high noise immunity and low power consumption characteristic of CMOS devices, along with the capability to drive 15 LS-TTL loads. This makes it suitable for interfacing with bus lines in bus-organized systems.

Key electrical specifications include a wide operating voltage range of 2V to 6V and a typical propagation delay of 15ns. The latch operates with a current draw of 7.8mA and features a Tri-State output, which allows all outputs to enter a high impedance state when the output control is high.

The device is housed in a 20-SOIC surface mount package, with a supplier device package also listed as 20-SOP. It operates within a temperature range of -40°C to 85°C. The 74HC logic family is speed, function, and pinout compatible with the 74LS logic family, and all inputs are protected against static discharge.

This latch is designed for applications requiring data retention and bus interfacing. Its 8:8 circuit configuration and independent circuits make it versatile for various digital system designs.
