Four bits of data from two sources can be selected using a Common Data Select input. The four outputs present the selected data in true (noninverted) form. The outputs may be switched to a high impedance state by placing a logic HIGH on the common Output Enable (OE) input, allowing the outputs to interface directly with bus-oriented systems. Features n n n n n n ICC and IOZ reduced by 50% Multiplexer expansion by tying outputs together Noninverting TRI-STATE outputs Outputs source/sink 24 mA ’ACT257 has TTL-compatible inputs Standard Military Drawing (SMD) — ’AC257: 5962-88703 — ’ACT.
