MC74HCT573ADWR2G

Latches Overview

The MC74HCT573ADWR2G is an octal transparent latch from the 74HCT logic family, manufactured by onsemi. It features eight D-type latches with non-inverting outputs in a 20-pin SOIC-Wide package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 30 ns and a static current of 4 uA. Output drive capabilities are specified at 6 mA for both low and high states. The component supports a minimum operating temperature of -55°C.

Latches Feature Summary

• Transparent latch operation allows data to pass directly to outputs when enabled.
• Octal configuration provides eight independent D-type latching channels.
• HCT logic series ensures compatibility with TTL-driven interfaces.

Latches Applications

• Parallel-to-serial data conversion circuits
• Registering microprocessor bus data
• Memory address buffering

Latches Procurement Notes

Verify the complete part number including the suffix ADWR2G to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed during assembly due to CMOS sensitivity.

Latches Selection Notes

Select this component when interfacing 5V HCT logic with external peripherals requiring latched data storage. The wide operating temperature range suits industrial environments. Compare against HC or ACT variants if different speed or voltage requirements exist.

Latches Part Context

This part belongs to the MC74HCT573A series of octal latches. It shares pinout compatibility with standard 74573 devices but utilizes HCT input thresholds. The WR2G suffix indicates specific reel packaging and lead-free manufacturing processes defined by onsemi.

Latches Replacement Considerations

Check for direct cross-reference part numbers from other manufacturers offering identical pinouts and electrical characteristics. Verify that substitute components meet the same HCT logic level requirements and package dimensions.
