MC74LCX257
Low-Voltage CMOS Quad
2-Input Multiplexer
With 5.0 V–Tolerant Inputs and Outputs
(3–State, Non–Inverting)
http://onsemi.com
The MC74LCX257 is a high performance, quad 2–input
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
MC74LCX257 inputs to be safely driven from 5.0 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 true
(non–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.
