General Description

The 'AC/'ACT257 is a quad 2-input multiplexer with TRI-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.

Features

  • 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
    • 'ACT257: 5962-89689
