MM74HC594N

Shift Registers Overview

The MM74HC594N is an 8-bit shift register with output latches manufactured by Fairchild Semiconductor. It operates within a supply voltage range of 2V to 6V and features true outputs. The device utilizes advanced silicon-gate CMOS technology, providing high noise immunity and low power consumption. It includes separate clocks for the shift register and storage register, along with a direct-overriding clear function. The component is housed in a 16-pin PDSO package.

Shift Registers Feature Summary

• Contains an 8-bit serial-in, parallel-out shift register feeding an 8-bit D-type storage register
• Provides 3-state outputs for effective bus line interfacing
• Features separate clocks for shift register and storage register operations
• Includes a direct-overriding clear input for immediate data reset

Shift Registers Applications

• Serial to parallel data conversion
• Capture and hold data for extended periods
• Microcontroller peripheral control expansion

Shift Registers Procurement Notes

Verify the manufacturer designation as Fairchild Semiconductor or its successor entities, as corporate acquisitions may affect branding on datasheets. Confirm the package type corresponds to the N suffix (PDSO-16) rather than tape-and-reel variants. Ensure the specific lot date code aligns with current production status requirements for your assembly process.

Shift Registers Selection Notes

Select this component when an 8-bit serial-to-parallel interface is required with latch functionality. The HC series offers compatibility with standard CMOS logic levels. Consider the 3-state output capability if multiple devices share a common bus structure. Verify that the operating voltage range of 2V to 6V matches the system power supply constraints.

Shift Registers Part Context

This part belongs to the 74HC594 family of high-speed CMOS shift registers. It is functionally equivalent to other manufacturers' 74HC594 components but carries the Fairchild Semiconductor branding. The 'N' suffix typically denotes a plastic small outline package variant suitable for surface mount applications.

Shift Registers Replacement Considerations

Direct substitutes include generic 74HC594 parts from other vendors such as Nexperia or Diodes Incorporated, provided they meet the same pinout and electrical specifications.
