MC74LCX258/D
MC74LCX258
Low−Voltage CMOS Quad
2−Input Multiplexer
With 5 V−Tolerant Inputs and Outputs
(3−State, Inverting)
The MC74LCX258 is a high performance, quad 2−input inverting
multiplexer with 3−state outputs operating from a 2.3 to 3.6 V supply.
High impedance TTL compatible inputs significantly reduce current
loading to input drivers while TTL compatible outputs offer improved
switching noise performance. A V
I
specification of 5.5 V allows
MC74LCX258 inputs to be safely driven from 5 V devices.
Four bits of data from two sources can be selected using the Select
input. The four outputs present the selected data in the inverted form.
The outputs may be switched to a high impedance state by placing a
logic HIGH on the Output Enable (OE
) input. Current drive capability
is 24 mA at the outputs.
