74HC595D-Q100,118

Shift Registers Overview

The Nexperia 74HC595D-Q100,118 is an automotive-grade 8-bit serial-in/serial or parallel-out shift register with output latches and 3-state outputs. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features separate clocks for the shift and storage registers, a serial input (DS), and a serial output (Q7S) for cascading. It includes an asynchronous reset (MR) input that clears the shift register on a LOW signal. Data transfers to the storage register occur on the LOW-to-HIGH transition of the STCP input. The component complies with AEC-Q100 Grade 1 standards.

Shift Registers Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standard
• Storage register with 3-state outputs controlled by OE input
• Shift register with direct clear via asynchronous MR input
• Input clamp diodes enable interfacing to voltages exceeding VCC

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify the specific ordering suffix matches the required package type, as the SO16 plastic small outline package corresponds to SOT109-1. Confirm the temperature range specification aligns with system requirements, noting availability for both -40 °C to +85 °C and -40 °C to +125 °C variants. Ensure design compliance with AEC-Q100 Grade 1 automotive standards before finalizing procurement specifications.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with independent storage and shift clocking is required for automotive environments. The 3-state outputs allow bus sharing, while the serial output facilitates daisy-chaining multiple devices. Verify logic level compatibility, as the HC series utilizes CMOS input levels. Consider thermal derating characteristics if operating near maximum power dissipation limits in confined spaces.

Shift Registers Part Context

This part belongs to the Nexperia 74HC595-Q100 family, which includes variants like the 74HCT595D-Q100. The family provides 8-bit serial-in/parallel-out functionality with 3-state outputs. Other package options include TSSOP16 and DHVQFN16. The product line is designed for high reliability in automotive applications, featuring robust ESD protection and compliance with JEDEC standards.

Shift Registers Replacement Considerations

The 74HCT595D-Q100,118 serves as a compatible alternative within the same family, differing primarily in TTL-compatible input levels compared to the CMOS levels of the HC variant.
