CD74AC373M

Latches Overview

The CD74AC373M is an octal transparent latch manufactured by Harris Corporation, belonging to the AC series of high-speed CMOS logic. It features eight D-type latches with tri-state outputs, designed for bus-oriented applications. The device operates on a single power supply ranging from 2V to 6V and supports a wide operating temperature range from -55°C to 125°C. It is housed in a 20-pin Small Outline Integrated Circuit (SOIC) package with a width of 0.295 inches (7.50mm).

Latches Feature Summary

• Provides eight independent transparent latches for data storage.
• Features tri-state outputs to facilitate bus driving.
• Constructed using high-speed AC series CMOS technology.

Latches Applications

• Bus-oriented memory mapping
• Register banks
• Temporary data storage

Latches Procurement Notes

Verify the manufacturer origin, as Harris Corporation's logic assets were acquired by Texas Instruments. Confirm the specific suffix 'M' corresponds to the SOIC-20 package variant. Check RoHS compliance status, as older Harris batches may not meet current environmental standards. Ensure the component is sourced from authorized distributors to avoid counterfeit parts.

Latches Selection Notes

Select this component when an octal latch with tri-state capability is required for high-speed digital systems. The AC series offers faster performance than standard HC logic. Consider the 20-SOIC package for surface-mount assembly. Verify voltage compatibility within the 2V to 6V range for the target application environment.

Latches Part Context

This part belongs to the 74AC logic family, known for superior speed compared to 74HC counterparts. It serves as a fundamental building block for digital circuits requiring parallel-to-serial conversion or data buffering. The CD74AC373M specifically denotes the Harris Corporation manufacturing version of this widely used latch IC.

Latches FAQ

What is the output state of the CD74AC373M?

The device features tri-state outputs, allowing it to drive buses effectively by entering a high-impedance state when disabled.

Is the CD74AC373M a registered or transparent latch?

It is a transparent latch, meaning the output follows the input when the enable signal is active.
