Overview
The 74AHCT164D14 is a serial input 8-bit edge-triggered shift register produced by Diodes Incorporated. This device is designed to convert serial input data into parallel output, making it a versatile component in digital circuitry. It features TTL-compatible inputs and operates within a supply voltage range of 4.5V to 5.5V. The shift register is triggered by a positive edge on the clock pulse (CP) pin, allowing data to be shifted from each stage to the next on each rising edge of the CP signal.
