DM74164中文资料8-Bit Serial In/Parallel Out Shift Registers数据手册TI规格书

描述 Description

General Description
These 8-bit shift registers feature gated serial inputs and an asynchronous clear. A LOW logic level at either serial input inhibits entry of the new data, and resets the first flip-flop to the LOW level at the next clock pulse, thus providing complete control over incoming data. A HIGH logic level on either input enables the other input, which will then determine the state of the first flip-flop. Data at the serial inputs may be changed while the clock is HIGH or LOW, but only information meeting the setup and hold time requirements will be entered. Clocking occurs on the LOW-to-HIGH level transition of the clock input. All inputs are diode-clamped to
minimize transmission-line effects.Features
