DUAL 4-INPUT

MULTIPLEXER WITH

3-STATE OUTPUTS

The MC74AC253/74ACT253 is a dual 4-input multiplexer with 3-state outputs. It

can select two bits of data from four sources using common select inputs. The

outputs may be individually switched to a high impedance state with a HIGH on the

respective Output Enable (OE) inputs, allowing the outputs to interface directly with

bus oriented systems.

• Multifunctional Capability

• Noninverting 3-State Outputs

• Outputs Source/Sink 24 mA

• ′ACT253 Has TTL Compatible Inputs
