1 / 8 page 54AC157 • 54ACT157 Quad 2-Input Multiplexer General Description The ’AC/’ACT157 is a high-speed quad 2-input multiplexer. Four bits of data from two sources can be selected using the common Select and Enable inputs. The four outputs present the selected data in the true (noninverted) form. The ’AC/ ’ACT157 can also be used as a function generator. Features n ICC and IOZ reduced by 50% n Outputs source/sink 24 mA n ’ACT157 has TTL-compatible inputs n Standard Microcircuit Drawing (SMD) — ’AC157: 5962-89539 — ’ACT157: 5962-89688 Logic Symbols Pin Names Description I 0a–I0d Source 0 Data Inputs I 1a–I1d Source 1 Data Inputs E Enable Input S Select Input Z a–Zd Outputs Connection Diagrams FACT™ is a trademark of Fairchild Semiconductor Corporation.
