简述:
8-bit serial-in, parallel-out shift register with Schmitt-trigger inputs
-
描述:
The 74HCS164 is an 8-bit serial-in/parallel-out shift register. The device features two serial data
inputs (DSA and DSB), eight parallel data outputs (Q0 to Q7). Data is entered serially through DSA
or DSB and either input can be used as an active HIGH enable for data entry through the other
input. Data is shifted on the LOW-to-HIGH transitions of the clock (CP) input. A LOW on the master
reset input (MR) clears the register and forces all outputs LOW, independently of other inputs.
Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to
voltages in excess of VCC.All inputs are Schmitt-trigger inputs, capable of transforming slowly changing input signals into
sharply defined, jitter-free output signals. - 数据手册:
