MC74HC595AMN1TWG-Q

Shift Registers Overview

The MC74HC595AMN1TWG-Q is an 8-bit serial-input/serial or parallel-output shift register with latched 3-state outputs. It consists of an 8-bit shift register and an 8-bit D-type latch. The device operates within a voltage range of 2.0 to 6.0 V, supports an operating temperature from -55°C to +125°C, and features a maximum propagation delay of 225 ns at 6.0 V. It utilizes a QFN-16 package.

Shift Registers Feature Summary

• Includes an asynchronous reset for the shift register and independent clock inputs for both the shift register and latch.
• Outputs directly interface to CMOS, NMOS, and TTL loads with high noise immunity characteristics.
• Qualified for automotive applications with AEC-Q100 certification and PPAP capability.

Shift Registers Applications

• Directly interfaces with SPI serial data ports on CMOS MPUs and MCUs
• Used in systems requiring unique site and control change requirements
• Automotive electronic applications

Shift Registers Procurement Notes

Verify that the specific ordering suffix MN1TWG-Q corresponds to the QFN-16 package and tape & reel shipping configuration as listed in the official datasheet. Confirm compliance with AEC-Q100 qualification standards and PPAP capability requirements before finalizing procurement specifications.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with latched 3-state outputs is required for space-constrained designs due to its QFN-16 footprint. Ensure the application environment falls within the specified -55°C to +125°C temperature range and operates between 2.0 V and 6.0 V supply voltages.

Shift Registers Part Context

This part belongs to the MC74HC595A family of high-performance silicon-gate CMOS logic devices. It offers improvements over standard HC595/HCT595 devices, including improved propagation delays, lower quiescent power consumption, and enhanced input noise and latchup immunity.

Shift Registers FAQ

What is the function of the Output Enable pin?

The Output Enable pin is active-low; a low signal allows data from the latches to be presented at the outputs, while a high signal forces the outputs into a high-impedance state.

How does the Reset input operate?

The Reset input is active-low and asynchronous. A low signal resets only the shift register portion of the device, leaving the 8-bit latch unaffected.
