  • TSSOP package may require specialized handling during assembly.

Working Principles

SN74HC165QPWREP operates as a parallel-to-serial shift register. When the SH/LD input is low, the data at the parallel inputs (QA-QD) is shifted into the register on each rising edge of the clock input (CLK). The serial data output (QH') reflects the shifted data. When the SH/LD input is high, the data at the parallel inputs is loaded into the register on the rising edge of the clock input.
