74HC165A RD1237 8-Bit Parallel In/Serial Out Shift Register IC

74HC165A RD1237 8-Bit Parallel In/Serial Out Shift Register IC

The 74HC165 high speed PARALLEL-IN/SERIAL-OUT SHIFT REGISTER utilizes advanced silicon-gate CMOS technology. It has the low power consumption and high noise immunity of standard CMOS integrated circuits, along with the ability to drive 10 LS-TTL loads. This 8-bit serial shift register shifts data from QA to QH 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. The 74HC logic family is functionally as well as pin-out compatible with the standard 74LS logic family. All inputs are protected from damage due to static discharge by internal diode clamps to VCC and ground.
