SN74HC165DRG4

Shift Registers Overview

The SN74HC165DRG4 is an 8-bit parallel-load shift register from the Texas Instruments HC logic family. It converts parallel data inputs into a serial output stream via a single line. The device operates on a supply voltage ranging from 2 V to 6 V and supports a wide operating temperature range of -40°C to +125°C. Key electrical parameters include propagation delays of 150 ns, 30 ns, and 26 ns under varying conditions. It utilizes positive-edge triggering for clock operations and features a parallel enable input for direct data loading. The component is housed in a 16-pin SOIC package suitable for surface mount technology.
