UNISONIC TECHNOLOGIES CO., LTD U74HCT165 CMOS IC 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 SOP-16 shift/load (SH/ LD ) input. The U74HCT165 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 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 ORDERING INFORMATION Ordering Number U74HCT165G-S16-R U74HCT165G-S16-R Package SOP-16 (1) Packing Type (1) R: Tape Reel (2) Package Type (2) S16: SOP-16 (3) Green Package (3) G: Halogen Free and Lead Free Packing Tape Reel MARKING www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 8 QW-R502-B32.B U74HCT165 CMOS IC PIN CONFIGURATION FUNCTION TABLE Operating Modes Parallel Load Serial Shift Hold “Do Nothing” Inputs Qn Registers Outputs SH/ LD CLK/INH CLK SER A to H Q0 Q1 to Q6 QH QH L L X X X X X X L H L H L to L H to H L H H L H L ↑ I X L q0 to q 5 q6 q6 H L ↑ h X H q0 to q 5 q6 q6 H ↑ L I X L q0 to q 5 q6 q6 H ↑ L h X H q0 to q 5 q6 q6 H H X X X Q0 q1 to q6 q7 q7 H X H X X Q0 q1 to q6 q7 q7 Notes: H=HIGH Voltage Level; h= HIGH Voltage Level one set-up time prior to the LOW-to-HIGH clock transition; L=LOW Voltage Level; l= LOW Voltage Level one set-up time prior to the LOW-to-HIGH clock transition; q=state of the referenced output one set-up time prior to the LOW-to-HIGH clock transition; X=don’t care; ↑= LOW-to-HIGH clock transition.
