74AC257 74ACT257 Quad 2-Input Multiplexer with 3-STATE Outputs November 1988 Revised November 1999 74AC257 74ACT257 Quad 2-Input Multiplexer with 3-STATE Outputs General Description Features The AC/ACT257 is a quad 2-input multiplexer with 3- I and I reduced by 50% CC OZ STATE outputs. Four bits of data from two sources can be Multiplexer expansion by tying outputs together selected using a Common Data Select input. The four out- Noninverting 3-STATE outputs puts present the selected data in true (noninverted) form. Outputs source/sink 24 mA The outputs may be switched to a high impedance state by placing a logic HIGH on the common Output Enable (OE) ACT257 has TTL-compatible inputs input, allowing the outputs to interface directly with bus-ori- ented systems.

It selects four bits of data from two sources under control of a Common Data Select input. When the Select Enable Input Inputs input is LOW, the I inputs are selected and when Select 0x OE SI I Z is HIGH, the I inputs are selected. The data on the 0 1 1x selected inputs appears at the outputs in true (noninverted) HX X X Z form. The device is the logic implementation of a 4-pole, 2- LH X L L position switch where the position of the switch is deter- mined by the logic levels supplied to the Select input. The LH X H H logic equations for the outputs are as follows: LL L X L Z = OE (1 S + I S) a 1a 0a LL H X H Z = OE (1 S + I S) b 1b 0b Z = OE (1 S + I S) H = HIGH Voltage Level c 1c 0c L = LOW Voltage Level Z = OE (1 S + I S) d 1d 0d X = Immaterial Z = High Impedance When the Output Enable (OE) is HIGH, the outputs are forced to a high impedance state. If the outputs are tied together, all but one device must be in the high impedance state to avoid high currents that would exceed the maxi- mum ratings. Designers should ensure the Output Enable signals to 3-STATE devices whose outputs are tied together are designed so there is no overlap.
