Overview

74AC257 • 74ACT257 Quad 2-Input Multiplexer with 3-STATE Outputs November 1988 Revised November 1999 74AC257 • 74ACT257 Quad 2-Input Multiplexer with 3-STATE Outputs General Description The AC/ACT257 is a quad 2-input multiplexer with 3STATE 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 (noninverted) form.
The outputs may be switched to a high impedance state by placing a logic HIGH on the common Output Enable (OE) input, allowing the outputs to interface directly with bus-oriented systems.
Features s ICC and IOZ reduced by 50% s Multiplexer expansion by tying outputs together s Noninverting 3-STATE outputs s Outputs source/sink 24 mA s ACT257 has TTL-compatible inputs Ordering Code: Order Number Package Number Package Description 74AC257SC M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.
