Product Descriptions
The AC/ACT257 is a quad 2-input multiplexer with 3- STATE outputs. 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.
Product Features
■ ICC and IOZ reduced by 50%
■ Multiplexer expansion by tying outputs together
■ Noninverting 3-STATE outputs
■ Outputs source/sink 24 mA
■ ACT257 has TTL-compatible inputs
