MC74HC595ADTR2G-Q

Shift Registers Overview

The MC74HC595ADTR2G-Q is an 8-bit serial-input/serial or parallel-output shift register with latched 3-state outputs, manufactured by onsemi. 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 for the HC variant. It features independent clocks for the shift register and storage register, along with an asynchronous reset for the shift register. The component is housed in a TSSOP-16 package.

Shift Registers Feature Summary

• Includes an 8-bit shift register feeding an 8-bit D-type storage latch with 3-state parallel outputs.
• Features independent clock inputs for the shift register and storage register, allowing stable parallel outputs during shifting.
• Provides an asynchronous active-low reset input that clears only the shift register portion.
• Outputs directly interface with CMOS, NMOS, and TTL loads.

Shift Registers Applications

• Directly interfaces with SPI serial data ports on CMOS MPUs and MCUs.
• Used as a serial-to-parallel converter.
• Functions as a data receiver in digital systems.

Shift Registers Procurement Notes

Verify the specific suffix 'Q' indicates AEC-Q100 qualification and PPAP capability, which requires unique site and control change requirements distinct from standard commercial versions. Confirm the package type matches the required footprint, as this part number specifies the TSSOP-16 configuration. Ensure compatibility with the intended operating voltage range of 2.0 to 6.0 V before integration.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with latched 3-state outputs is required for SPI interfacing. The HC logic family supports a wide operating voltage range of 2.0 to 6.0 V. The '-Q' suffix denotes automotive qualification and specific manufacturing controls. Consider the TSSOP-16 package dimensions if space constraints are a factor compared to SOIC or QFN options.

Shift Registers Part Context

This device belongs to the MC74HC595A series, which includes improvements over previous generations such as improved propagation delays, 50% lower quiescent power, and enhanced input noise and latchup immunity. It is fabricated using high-performance silicon-gate CMOS technology. The series is designed to be pin and function compatible with other standard logic families while offering higher performance characteristics.
