MC74HCT573AN

Latches Overview

The MC74HCT573AN is an octal transparent latch manufactured by onsemi, belonging to the HCT logic series. It features eight D-type latches with three-state outputs in a 20-pin DIP package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports propagation delays of 30 ns at 5 V. It exhibits low static current consumption of 4 uA and provides output drive capabilities of 6 mA for both high and low states. The component functions as a non-inverting latch suitable for bus-oriented applications.

Latches Feature Summary

• Transparent latch operation allows data to pass directly from input to output when enabled.
• Three-state outputs facilitate connection to system buses without external switching components.
• CMOS construction ensures low power consumption while maintaining compatibility with TTL inputs.

Latches Applications

• Bus-oriented memory mapping
• Registering high-performance microprocessor systems
• Parallel I/O expansion

Latches Procurement Notes

Verify the specific suffix 'AN' corresponds to the 20-pin PDIP package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure moisture sensitivity handling protocols are followed during assembly processes.

Latches Selection Notes

Select this component for designs requiring octal latching with bus isolation. Compare against MM74HCT573 variants for package differences. Verify temperature range requirements against industrial specifications if operating outside standard commercial limits.

Latches Part Context

This part belongs to the 74HCT573 family of octal transparent latches. It serves as a digital storage element in CMOS technology. The HCT series provides fast switching speeds compatible with standard TTL logic levels, making it suitable for general-purpose digital interfacing tasks.

Latches Replacement Considerations

Direct substitutes include SN74HCT573N from Texas Instruments. Alternative sources may offer equivalent functionality in different packages such as SOIC or TSSOP formats.
