Product details

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 effects Y Guaranteed 4000V minimum ESD protection Commercial 74F257APC 74F257ASC (Note 1) 74F257ASJ (Note 1) Military 54F257ADM (Note 2) 54F257AFM (Note 2) 54F257ALL (Note 2) Package Number N16E J16A M16A M16D W16A E20A Package.
