MC74HC373ANG

Latches Overview

The MC74HC373ANG is an octal 3-state non-inverting transparent latch manufactured by onsemi using high-performance silicon-gate CMOS technology. It operates within a supply voltage range of 2.0 V to 6.0 V and features eight D-type latches with independent inputs. The device includes shared latch enable (LE) and output enable (OE) controls, allowing data transparency when LE is high and storage upon the falling edge. Outputs enter a high-impedance state when OE is high, facilitating bus-oriented applications while maintaining low static power consumption.

Latches Feature Summary

• Octal 3-state non-inverting transparent latch architecture
• High-performance silicon-gate CMOS construction
• Shared latch enable and output enable control lines

Latches Applications

• Bus-oriented memory mapping
• Working registers
• I/O address decoding

Latches Procurement Notes

Verify package compatibility for the SOIC-20 configuration. Confirm RoHS compliance status as indicated in official documentation. Ensure operating temperature ranges align with system requirements, noting potential variations between industrial and extended grades. Cross-reference datasheet revisions to confirm pinout consistency with existing designs.

Latches Selection Notes

Select this component for designs requiring parallel data storage with tri-state bus interfacing capabilities. The HC series offers speed and power characteristics compatible with LSTTL logic levels. Consider the wide supply voltage range for flexible power domain integration. Verify that the latch enable timing meets system setup and hold requirements.

Latches Part Context

This part belongs to the 74HC373 family of octal latches. It is functionally similar to other 74HC series transparent latches but distinguished by its specific package and manufacturer specifications. The device serves as a standard interface element for digital systems requiring temporary data storage and controlled output driving.

Latches Replacement Considerations

MC74HC573A is a functional equivalent with identical logic but different pinout. MC74HC533 and MM74HC533 are compatible with inverted outputs. Check datasheets for exact pin correspondence before substitution.
