Product Description:
The 74ALS164D from NXP is a member of the 74ALS series logic devices, known for their balance between speed and power consumption. This device features a serial data input (DS), a clock input (CP), and eight parallel outputs (Q0 to Q7). Each time the clock input is pulsed, the data present at the DS input is shifted into the register and subsequently appears at the Q outputs.
The tri-state output feature allows for multiple registers to be connected in parallel, enabling easy expansion of the data bus width. When the output enable (OE) input is high, the outputs are in a high-impedance state, which is particularly useful for interfacing with buses and for implementing wired-OR logic configurations.
Designed to be used in systems that require low power consumption without sacrificing speed, the 74ALS164D is fabricated with silicon gate CMOS technology. The device is available in a 14-pin SOIC package, which is suitable for surface mount technology (SMT) and offers a compact footprint on printed circuit boards (PCBs).
Whether you are developing data buffers, shift registers, or need a reliable component for your digital designs, the 74ALS164D offers a robust and efficient solution for your serial-to-parallel data conversion needs.
