1 / 8 page 54AC253 • 54ACT253 Dual 4-Input Multiplexer with TRI-STATE® Outputs General Description The ’AC/’ACT253 is a dual 4-input multiplexer with TRI-STATE outputs. It can select two bits of data from four sources using common select inputs. The outputs may be in- dividually 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. Features n ICC and IOZ reduced by 50% n Multifunction capability n Noninverting TRI-STATE outputs n Outputs source/sink 24 mA n ’ACT253 has TTL-compatible inputs n Standard Military Drawing (SMD) — ’AC253: 5962-87693 — ’ACT253: 5962-87761 Logic Diagrams Pin Names Description I 0a–I3a Side A Data Inputs I 0b–I3b Side B Data Inputs S 0,S1 Common Select Inputs OE a Side A Output Enable Input OE b Side B Output Enable Input Z a,Zb TRI-STATE Outputs TRI-STATE® is a registered trademark of National Semiconductor Corporation.
