Product Overview
The SN74ACT165PWR from Texas Instruments is an 8-bit parallel-to-serial shift register designed for high-speed data conversion in digital systems. It operates with a wide supply voltage range of 4.5V to 5.5V, making it suitable for 5V logic applications. The device features parallel load capability, allowing simultaneous loading of 8 bits of data, and serial output for cascading multiple devices. Packaged in a compact 16-TSSOP, it is ideal for space-constrained designs.
