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 by placing a logic HIGH on the common Output Enable (OE) input, allowing the outputs to interface directly with bus-oriented systems. FEATURES
s ICC and IOZ reduced by 50% s Multiplexer expansion by tying outputs together s Noninverting 3-STATE outputs s Outputs source/sink 24 mA s ACT257 has TTL-compatible inputs Ordering Code: Order Number Package Number Package DESCRIPTION
