1 / 8 page ![]() UNISONIC TECHNOLOGIES CO., LTD U74HCT165 CMOS IC www.unisonic.com.tw 1 of 8 Copyright © 2015 Unisonic Technologies Co., Ltd QW-R502-B32.B 8-BIT PARALLEL-LOAD SHIFT REGISTER DESCRIPTION The U74HCT165 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 these are enabled by a low level at shift/load (SH/ LD ) input. The U74HCT165 also features a clock-inhibit (CLK INH) function and a complementary serial ( H Q ) output. Clocking is accomplished by a low-to-high transition of the 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. The inputs are compatible with TTL,NMOS and CMOS output voltage levels. FEATURES * Complementary Outputs * Direct Overriding Load (Data) Inputs * Gated Clock Inputs * Parallel-to-Serial Data Conversion * Compatible with TTL, NMOS, CMOS output voltage levels SOP-16 ORDERING INFORMATION Ordering Number Package Packing U74HCT165G-S16-R SOP-16 Tape Reel U74HCT165G-S16-R (1) Packing Type (2) Package Type (3) Green Package (1) R: Tape Reel (2) S16: SOP-16 (3) G: Halogen Free and Lead Free MARKING |
