Overview
MC74AC253, MC74ACT253
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 • These are Pb−Free Devices
