hd74ac165/hd74act165 parallel-load 8-bit shift register ade-205-374 (z) 1st. edition sep. 2000 description this 8-bit serial shift register shifts data from q a to q h when clocked, parallel inputs to each stage are enabled by a low level at the shift/load input. also included is a gated clock input and a complementary output from the eighth bit. clocking is accomplished through a 2-input nor gate permitting one input to be used as a clock inhibit function. holding either of the clock inputs high inhibits clocking, and holding either clock input low with the shift/load input high enables the other clock input. data transfer occurs on the positive going edge of the clock. parallel loading is inhibited as long as the shift/load input is high. when taken low, data at the parallel inputs is loaded directly into the register independent of the state of the clock. features outputs source/sink 24 ma hd74act165 has ttl-compatible inputs
