CD74AC175M

Overview

The CD74AC175M is a CMOS D-type flip-flop from the AC series, manufactured by Harris Corporation. It integrates four independent positive edge-triggered D flip-flops within a single package. The device features complementary outputs for each flip-flop and operates on a supply voltage range of 2V to 6V. It is housed in a 16-pin SOIC surface-mount package. The component supports an operating temperature range from -55°C to +125°C and has a maximum propagation delay of 220 ns at a nominal supply voltage.

Feature Summary

• Integrates four independent positive edge-triggered D flip-flops
• Provides complementary output signals for each data bit
• Operates across a wide industrial temperature range

Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• General-purpose digital storage applications

Procurement Notes

Verify the manufacturer origin carefully, as Harris Corporation's logic assets were acquired by Texas Instruments. Ensure the specific suffix 'M' corresponds to the SOIC package variant. Confirm RoHS compliance status, as older Harris production runs may not meet current environmental standards. Validate that the source document explicitly identifies Harris Corporation as the original designer or manufacturer for this part number.

Selection Notes

Select this component when four synchronized D flip-flops are required in a compact surface-mount form factor. The AC series offers higher speed performance compared to standard HC/UH variants. Ensure the design accommodates the 2V to 6V supply voltage range and utilizes the complementary outputs if differential signaling is necessary. Verify that the 16-pin SOIC footprint matches the PCB layout requirements.

Part Context

This component belongs to the 74AC logic family, which provides faster switching speeds than the standard 74HC series while maintaining similar pinouts. The CD74 prefix indicates a commercial temperature grade device originally designed by Harris Corporation. The 'M' suffix specifically denotes the 16-pin small-outline integrated circuit (SOIC) package configuration.
