CD74HCT166M TI Shift Register | 16-SOIC | 8-bit, Parallel-to-Serial

Product Overview

The CD74HCT166M is a high-speed CMOS 8-bit parallel-in/serial-out shift register from Texas Instruments. It features a wide operating voltage range of 4.5V to 5.5V, making it ideal for 5V logic systems. The device accepts parallel data inputs (D0–D7) and shifts them out serially (QH) under control of a clock (CP) and shift/load (SH/LD) input. It also includes an asynchronous master reset (MR) and output enable (OE) for flexible system integration. Packaged in a 16-pin SOIC, it is suitable for space-constrained applications.
