74HC590PW-Q100J

Shift Registers Overview

The Nexperia 74HC590PW-Q100 is an 8-bit binary counter with a storage register and 3-state outputs, qualified to AEC-Q100 Grade 1. It operates on a supply voltage of 2.0 V to 6.0 V within a temperature range of -40 °C to +125 °C. The device features separate positive edge-triggered clocks for the counter (CPC) and register (CPR), a master reset (MRC), and count enable (CE). It includes a ripple carry output (RCO) for cascading and clamp diodes on inputs.

Shift Registers Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards
• Separate clock inputs for independent counter and register operation
• High noise immunity and low power CMOS dissipation
• ESD protection exceeding 2000 V HBM and 1000 V CDM

Shift Registers Applications

• Automotive electronic systems requiring robust logic components
