| HD74AC166/HD74ACT166 8-bit Shift Register Description The HD74AC166/HD74ACT166 is an 8-bit, serial or parallel-in, serial-out shift register using edge triggered D-type flip-flops. Serial and parallel entry are synchronous, with state changes initiated by the rising edge of the clock. An asynchronous Master Reset overrides other inputs and clears all flip-flops. The circuit can be clocked from two sources or one CP input can be used to trigger the other.

When one of the clock inputs is used as an active High clock inhibt, it should attain the High state while the other clock is still in the High state following the previous operation. When the Parallel Enable (PE) input is Low, data is loaded into the register from the Parallel Data (P0 to P7) inputs on the next rising edge of the clock. When PE is High, information is shifted from the Serial Data (DS) input to Q0 and all data in the register is shifted one bit position (i.e., Q0 Q1, Q1 Q2, etc.) on the rising edge of the clock. 2 HD74AC166/HD74ACT166 Truth Table Inputs Parallel MR L H H H H H H: L: X: : PE X X L H H X CP 2 X L L L L H CP 1 X L DS X X X H L X P0 to P7 X X a *** h X X X Internal Outputs Q0 L QA0 a H L QA0 Q6 L QB0 b QAn QAn QB0 Output Q7 L QH0 h QGn QGn QH0 High Voltage Level Low Voltage Level Immaterial Low-to-High Clock Transition Logic Diagram P0 DS P1 P2 P3 P4 P5 P6 MR P7 PE CP 12 R CP S CD Q R CP S CD Q Q7 3 HD74AC166/HD74ACT166 DC Characteristics (unless otherwise specified) Item Maximum quiescent supply current Maximum quiescent supply current Maximum additional ICC/input (HD74ACT166) Symbol I CC I CC I CCT Max 80 8.0 1.5 Unit A A mA Condition VIN = VCC or ground, VCC = 5.5 V, Ta = Worst case VIN = VCC or ground, VCC = 5.5 V, Ta = 25C VIN = VCC - 2.1 V, VCC = 5.5 V, Ta = Worst case AC Characteristics: HD74AC166 Ta = +25C CL = 50 pF Item Maximum clock frequency Propagation delay CP 1 or CP2 to Q 7 Propagation delay CP 1 or CP2 to Q 7 Propagation delay MR to Q 7 Note: t PHL t PHL t PLH Symbol f max VCC (V)*1 3.3 5.0 3.3 5.0 3.3 5.0 3.3 5.0 Min 75 100 1.0 1.0 1.0 1.0 1.0 1.0 Typ -- -- 11.0 9.5 10.5 9.0 9.5 6.5 Max -- -- 14.5 11.5 14.0 11.0 12.0 9.0 Ta = -40C to +85C CL = 50 pF Min 65 80 1.0 1.0 1.0 1.0 1.0 1.0 Max -- -- 15.5 12.5 15.0 12.0 13.0 10.0 ns Unit MHz 1.
