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 VCC OEb S0 I3b I2b I1b I0b Zb 16 15 14 13 12 11 10 9 12345678 OEa S1 I3a I2a I1a I0a Za GND Figure 1.
