74HC164数据手册集成电路（IC）的移位寄存器规格书PDF

描述 Description

The 74HC164 is an 8-bit serial-in and parallel-out shift register which can accept a wide supply voltage range from 2.0V to 5.5V.
This device provides gated serial inputs (DSA and DSB) and parallel data outputs (Q0 to Q7). DSA and DSB support serial data entry, where either input can allow data to enter through another input as an active high input. CP is a clock input. When the device is on low-to-high clock transition of the CP, data can be shifted. MR is the master reset input that is separated from the other inputs. When MR is held low, it can make the register clear and all outputs must be low level. The clamp diodes of inputs allow the use of current limiting resistors to connect inputs to the voltage exceeding supply voltage.
