MM74HC595WM

Shift Registers Overview

The MM74HC595WM is an 8-bit serial-in, parallel-out shift register with output latches manufactured by Fairchild Semiconductor. It operates within a supply voltage range of 2V to 6V and supports an industrial temperature range from -40°C to 85°C. The device utilizes CMOS technology and is housed in a 16-lead Small Outline Integrated Circuit (SOIC) package with a width of 0.154 inches (3.90mm). It features true outputs and is RoHS compliant.

Shift Registers Feature Summary

• Converts serial input data into parallel output via internal shift and storage registers
• Provides direct connection capability for LED displays or decimal counters
• Supports cascading operations through the serial output pin for expanded bit capacity

Shift Registers Applications

• LED display systems requiring serial-to-parallel conversion
• Decimal counter circuits
• Industrial control systems utilizing serial data expansion

Shift Registers Procurement Notes

Verify the specific suffix 'WM' against the manufacturer's official datasheet to confirm package dimensions and tape-and-reel specifications. Ensure the component meets the required industrial temperature grade (-40°C to 85°C) for your application environment. Cross-reference the part number with current Fairchild or ON Semiconductor documentation to confirm active status and compliance with relevant environmental directives.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with parallel latching is required in a surface-mount SOIC-16 footprint. It is suitable for designs needing operation across a wide voltage range of 2V to 6V. Consider this part for applications where serial data expansion is necessary without consuming multiple microcontroller I/O pins.

Shift Registers Part Context

This component belongs to the HC/UH series of high-speed CMOS logic devices. It is functionally compatible with other 74HC595 variants from different manufacturers, such as Texas Instruments' SN74HC595. The MM prefix typically denotes commercial/industrial grade variants produced by Fairchild Semiconductor.
