MC74AC573MEL

Latches Overview

The MC74AC573MEL is an octal transparent D-type latch manufactured by onsemi, belonging to the 74AC logic series. It features eight D-type latches with three-state outputs and operates within a supply voltage range of 2V to 6V. The device provides high drive capability with output currents of 24mA at both high and low states. Propagation delay is specified at 13ns when operating at 3.3V and reduces to 10ns at 5V. Static current consumption is limited to 8uA maximum. The component is housed in a 20-SOIC package and supports surface mount installation.

Latches Feature Summary

• Octal configuration providing eight independent transparent D-type latches for parallel data storage
• Three-state outputs allowing direct connection to bus-oriented systems without additional interface hardware
• High drive strength capable of sourcing and sinking 24mA for robust signal integrity
• Wide operating voltage range supporting compatibility with 2V through 6V power domains

Latches Applications

• Bus-oriented memory register implementations
• I/O port expansion circuits
• Mobile applications requiring low power consumption
• Consumer electronics utilizing CMOS technology

Latches Procurement Notes

Verify the specific suffix EL against the official onsemi datasheet to confirm package dimensions and tape/reel specifications. Ensure the procurement source provides valid RoHS compliance documentation as required for modern electronic assemblies. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current production status and availability constraints before finalizing orders.

Latches Selection Notes

Select this component when designing systems requiring octal latching with three-state bus interfacing capabilities. The AC series offers faster propagation speeds compared to standard 74LS equivalents while maintaining CMOS power efficiency. Consider the 2V to 6V operating range to ensure compatibility with the target system's voltage rails. Verify that the 20-SOIC package footprint aligns with the printed circuit board layout requirements.

Latches Part Context

This device is part of the broader 74AC family of high-speed CMOS logic devices produced by onsemi. It serves as a digital storage element within sequential logic circuits. The MC74AC573 variant specifically denotes the octal latch configuration with three-state outputs. It is distinct from non-latching buffers or inverters within the same logic family due to its data retention capability controlled by the latch enable input.

Latches Replacement Considerations

Compatible substitutes include the MC74AC573DWG and MC74AC573DTR2G from onsemi, which share identical logical functionality but differ in packaging formats such as SOIC or TSSOP. Other manufacturers may offer equivalent parts under different naming conventions within the 74AC logic family.
