SN74AHCT595PW

Shift Registers Overview

The SN74AHCT595PW is an 8-bit serial-in, parallel-out shift register with a storage register and 3-state outputs. It operates on a single supply voltage of 4.5V to 5.5V within an ambient temperature range of -40°C to 125°C. The device features TTL-compatible inputs, a direct clear input for the shift register, and separate positive-edge triggered clocks for shifting and storage. It is housed in a 16-pin TSSOP package.

Shift Registers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current Package Option Addendum to confirm production status and material specifications. Confirm that the component meets RoHS compliance requirements and matches the intended thermal and mechanical constraints for the target application environment.

Shift Registers Selection Notes

Select this component when a low-drive CMOS shift register is required to minimize output ringing and overshoot in bus interface applications. Ensure the design accommodates the specified operating voltage range and utilizes bypass capacitors near power pins to prevent disturbances during operation.

Shift Registers Part Context

This part belongs to the SNx4AHCT595 family of 8-bit shift registers manufactured by Texas Instruments. It provides a serial-to-parallel conversion function suitable for digital logic systems requiring data expansion or buffering capabilities.

Shift Registers FAQ

How are unused inputs handled?

Unused inputs must not be left floating; they should be connected to a high or low bias to prevent undefined operational states.

What is the function of the SRCLR pin?

The SRCLR pin provides a direct overriding clear for the shift register, resetting its state independently of the clock signals.
