IN74HC165AN中文资料8-Bit Serial or Parallel-Input/Serial-Output Shift Register数据手册IKsemicon规格书

描述 Description

The IN74HC165A isidenticalinpinoutto  the LS/ALS165. The device inputs are compatiblewithstandard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.
This device is an 8-bitshiftregister withcomplementaryoutputs from the last stage. Data may beloadedintothe register either inparallel orin serial form.  When the SerialShift/ParallelLoad inputislow, the datais loaded asynchronouslyinparallel.When the SerialShift/Parallel Load input ishigh, the dataisloaded seriallyon the rising edge of either Clock or Clock Inhibit(see the Function Table).
The 2-inputNORclock maybe used either bycombining two independentclock sources or bydesignating one of the clock inputs toact as a clock inhibit.

•  Outputs Directly Interface to CMOS, NMOS, and TTL
•  Operating Voltage Range:2.0 to6.0 V
•  Low InputCurrent:1.0 µA
•  High Noise Immunity Characteristic of CMOS Devices
