Shift Registers Procurement Notes

Verify that the ordering suffix matches the required package type and lead time specifications. Confirm compliance with RoHS directives and ensure the component meets the specific AEC-Q100 reliability requirements for your target automotive application environment before finalizing procurement orders.

Shift Registers Selection Notes

Select this component when an 8-bit parallel-to-serial conversion is required in space-constrained automotive designs. The WQFN-16 package with wettable flanks is suitable for high-reliability surface-mount assembly. Ensure the system controller can handle the serial data rate and timing constraints defined in the switching characteristics.

Shift Registers Part Context

This part belongs to the SN74AHC165-Q1 family of automotive logic devices. It serves as a parallel-input shift register designed to reduce the number of inputs required on a system controller. The device integrates an 8-bit D-type storage register fed by the shift register, providing flexible data handling capabilities for embedded systems.

Shift Registers FAQ

How does the SH/LD input control data loading?

When the SH/LD input is low, the device performs a parallel load of the values at inputs A through H into the internal memory registers. When high, it allows shifting operations based on the clock state.

What is the function of the CLK INH input?

The CLK INH (clock inhibit) input prevents the shift register from clocking data when held high. Shifting only occurs when CLK INH is low and the clock signal transitions.
