SN74AHCT595NSRG4

Shift Registers Overview

The SN74AHCT595NSRG4 is an 8-bit serial-in, parallel-out shift register with a storage register and 3-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V. The device features TTL-voltage compatible inputs and provides a direct clear input for the shift register. Both the shift register clock (SRCLK) and storage register clock (RCLK) are positive-edge triggered. The component is housed in a 16-pin SOIC package.

Shift Registers FAQ

How does the device handle unused inputs?

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.
