UNISONIC TECHNOLOGIES CO., LTD U74HC165 CMOS IC 8-BIT PARALLEL-LOAD SHIFT REGISTER  DESCRIPTION SOP-16 The U74HC165 is an 8-bit parallel-load shift register that, when clocked, shifts the data toward a serial (QH) output. Parallel-in access to each stage is provided by eight individual direct data (A-H) inputs that are enabled by a low level at shift/load (SH/ LD ) input. The U74HC165 also features a clock-inhibit (CLK INH) function and a complementary serial ( QH ) output. Clocking is accomplished by a low-to-high transition of the TSSOP-16 clock (CLK) input while SH/ LD is held high and CLK INH is held low. The functions of CLK and CLK INH are interchangeable. Since a low CLK and a low-to-high transition of CLK INH also accomplish clocking, CLK INH should be changed to the high level only while CLK is high. Parallel loading is inhibited when SH/ LD is held high. While SH/ LD is low, the parallel inputs to the register are enabled independently of the levels of the CLK, CLK INH, or serial (SER) inputs.  FEATURES * Complementary Outputs * Direct Overriding Load (Data) Inputs * Gated Clock Inputs * Parallel-to-Serial Data Conversion  ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74HC165L-S16-R U74HC165G-S16-R U74HC165L-P16-R U74HC165G-P16-R  Package Packing SOP-16 TSSOP-16 Tape Reel Tape Reel MARKING www.unisonic.com.tw Copyright © 2023 Unisonic Technologies Co., Ltd 1 of 9 QW-R502-A44.F  PDF
