Description
The SN74HC165 SOP16 device is an 8-bit parallel-load shift register designed for rapid parallel-to-serial data conversion.
With eight direct data inputs (A–H) enabled via the shift/load (SH/LD) pin and complementary serial output (QH), this IC allows flexible data capture and shifting with ease.
Ideal for applications requiring efficient parallel data acquisition and serial communication, the SN74HC165 offers features such as an optional clock-inhibit function and gated clock inputs.
Its versatile clocking with interchangeable CLK and CLK INH functions ensures precise timing control in your digital systems.
