MM74HC251 8-Channel 3-STATE Multiplexer
September 1983 Revised February 1999
MM74HC251 8-Channel 3-STATE Multiplexer
General Description
The MM74HC251 8-channel digital multiplexer with 3STATE outputs utilizes advanced silicon-gate
CMOS technology.
Along with the high noise immunity and low power consumption of standard
CMOS integrated circuits, it possesses the ability to drive 10 LS-TTL loads.
The large output drive capability and 3-STATE feature make this part ideally suited for interfacing with bus lines in a bus oriented system.
This multiplexer features both true (Y) and complement (W) outputs as well as a STROBE input.
The STROBE must be at a low logic level to enable this device.
