M74HC251 - 8 BIT SIPO SHIFT REGISTER

Datasheet Summary

Description

The M54/74HC251 is a high speed CMOS 8-CHANNEL MULTIPLEXER (3-STATE) fabricated in silicon 2 gate C MOS technology.

It has the same high speed performance of LSTTL combined with true CMOS low power consumption.

Features

  • both true (Y) and complement (W) outputs as well as STROBE input. The STROBE must be a low logic level to enable this device. When the STROBE input is high, both outputs are in the high impedance state. When enabled, address information on the data select inputs determines which data input is routed to Y and W. All inputs are equipped with protection circuits against static discharge and transient excess voltage. PIN.
