Overview

54F 74F257A Quad 2-Input Multiplexer with TRI-STATE Outputs November 1994 54F 74F257A Quad 2-Input Multiplexer with TRI-STATE Outputs General Description The ’F257A 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 (non-inverted) form The outputs may be switched to a high impedance state with a HIGH on the common Output Enable (OE) input allowing the outputs to interface directly with bus-oriented systems Features Y Multiplexer expansion by tying outputs together Y Non-inverting TRI-STATE outputs Y Input clamp diodes limit high-speed termination effect...
