54F 74F253 Dual 4-Input Multiplexer with TRI-STATE Outputs
November 1994
54F 74F253 Dual 4-Input Multiplexer with TRI-STATE Outputs
General Description
The 'F253 is a dual 4-input multiplexer with TRI-STATE o utputs It can select two bits of data from four sources using common select inputs The output may be individually switched to a high impedance state with a HIGH on the respective Output Enable (OE) inputs allowing the outputs to interface directly with bus oriented systems

Functional Description
This device contains two identical 4-input multiplexers with TRI-STATE outputs They select two bits from four sources selected by common Select inputs (S0 S1) The 4-input multiplexers have individual Output Enable (OEa OEb) inputs which when HIGH force the outputs to a high impedance (High Z) state This device is the logic implementation of a 2-pole 4-position switch where the position of the switch is determined by the logic levels supplied to the two select inputs ZThe logic equations for the outputs are shown below

If the outputs of TRI-STATE devices are tied together all but one device must be in the high impedance state to avoid high currents that would exceed the maximum ratings Designers should ensure that Output Enable signals to TRISTATE devices whose outputs are tied together are designed so that there is no overlap
