hd74ac166/hd74act166 8-bit shift register ade-205-375 (z) 1st. edition sep. 2000 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. features outputs source/sink 24 ma hd74act166 has ttl-compatible inputs pin arrangement 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 d s p 0 p 1 p 2 p 3 cp 1 cp 2 gnd v cc pe p 7 q 7 p 6 p 5 p 4 mr (top view)
