74AHC594D-Q100,118

Shift Registers Overview

The Nexperia 74AHC594D-Q100,118 is an automotive-qualified, high-speed Si-gate CMOS 8-bit shift register with an output storage register. It operates within a supply voltage range of 2.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features independent clocks for the shift and storage registers, along with direct overriding clears for both sections. It utilizes a 16-lead SO plastic small outline package (SOT109-1) with a body width of 3.9 mm.

Shift Registers Feature Summary

• Automotive product qualification in accordance with AEC-Q100 Grade 1 standard
• Independent positive-edge triggered clocks for shift and storage registers
• Direct overriding clear inputs for both shift and storage registers
• High noise immunity with Schmitt-trigger action on all inputs

Shift Registers Applications

• Serial-to-parallel data conversion
• Remote control holding register

Shift Registers Procurement Notes

Verify that the specific part number suffix matches the required package type, as the base logic family is available in multiple form factors including TSSOP and DHVQFN. Confirm the operating temperature grade aligns with system requirements, noting that this specific variant is specified up to +125 °C. Ensure design compliance with the absolute maximum ratings provided in the datasheet regarding supply voltage and current limits.

Shift Registers Selection Notes

Select this component when an 8-bit serial-in parallel-out shift register with separate storage is required for automotive environments. It serves as a pin-compatible alternative to Low-Power Schottky TTL devices. Consider the wide supply voltage capability if interfacing with mixed voltage domains. Verify that the push-pull output configuration meets the load requirements of the destination circuitry.
