MC74HC595ADR2G-Q

Shift Registers Overview

The MC74HC595ADR2G-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 and supports an operating temperature from -55°C to +125°C. Propagation delays are specified at 140 ns, 100 ns, 28 ns, and 24 ns depending on conditions. It features asynchronous reset, independent clock inputs for shift and latch operations, and direct interface capability with SPI ports.

Shift Registers Feature Summary

• AEC-Q100 qualified and PPAP capable for automotive applications requiring unique site and control change requirements.
• High-performance silicon-gate CMOS technology providing improved propagation delays and lower quiescent power compared to standard HC595/HCT595.
• Outputs directly interface to CMOS, NMOS, and TTL loads with high noise immunity characteristics.

Shift Registers Applications

• Automotive electronic systems requiring specific site and control change protocols.
• SPI serial data port interfacing with CMOS microprocessors and microcontrollers.
• Applications necessitating robust latchup immunity and extended temperature operation.

Shift Registers Procurement Notes

Verify the AEC-Q100 qualification status and PPAP capability when sourcing this component for automotive use. Confirm that the ordering suffix '-Q' corresponds to the required manufacturing site and control change specifications mandated by your application standards. Ensure compliance with RoHS and halogen-free requirements as stated in the datasheet.

Shift Registers Selection Notes

Select this variant over standard versions when automotive qualification (AEC-Q100) and PPAP documentation are mandatory. The '-Q' suffix indicates adherence to specific site and control change requirements distinct from the standard MC74HC595ADR2G. Consider the extended temperature range and enhanced latchup immunity if operating in harsh environments.

Shift Registers Part Context

This component belongs to the MC74HC595A family of 8-bit shift registers. It shares the core functional architecture with the MC74HC595ADR2G but includes the '-Q' suffix denoting automotive-grade qualification. The device integrates an 8-bit shift register feeding an 8-bit storage register with tri-state parallel outputs, designed for high-speed serial-to-parallel conversion.

Shift Registers FAQ

What does the '-Q' suffix indicate for this part number?

The '-Q' suffix denotes that the device is AEC-Q100 qualified and PPAP capable, intended for automotive and other applications requiring unique site and control change requirements.

Does the Output Enable pin affect the serial output?

No, the Output Enable pin forces the parallel outputs (QA-QH) into a high-impedance state but does not affect the serial output (SQH).
