GENERAL DESCRIPTION
Four bits of data from two sources can be selected using a common data select input. The outputs may be switched to a high impedance state with a HIGH on the common Output Enable (OE) input, allowing the outputs to interface directly with bus-oriented systems. n n n n n Multiplexer expansion by tying outputs together Inverting TRI-STATE outputs Outputs source/sink 24 mA ’ACT258 has TTL-compatible inputs Standard Military Drawing (SMD) — ’ACT258: 5962-88704 — ’AC258: 5962-91604FEATURES
