简述:
8-bit parallel-in/serial out shift register with Schmitt-trigger
inputs -
描述:
The 74HCS165 is an 8-bit serial or parallel-in/serial-out shift register. The device features a serial
data input (DS), eight parallel data inputs (D0 to D7) and two complementary serial outputs (Q7
and Q7). When the parallel load input (PL) is LOW the data from D0 to D7 is loaded into the shift
register asynchronously. When PL is HIGH data enters the register serially at DS. When the clock
enable input (CE) is LOW data is shifted on the LOW-to-HIGH transitions of the CP input. A HIGH
on CE will disable the CP input. 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:
