Overview: Quad 2-Input Multiplexer with 3-State Outputs MC74AC257, MC74ACT257 The MC74AC257/74ACT257 is a quad 2−input multiplexer with 3−state outputs. Four bits of data from two sources can be selected using a mon 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 mon Output Enable (OE) input, allowing the outputs to interface directly with bus−oriented systems. • Multiplexer Expansion by Tying Outputs Together • Noninverting 3−State Outputs • Outputs Source/Sink 24 mA • ′ACT257 Has TTL patible Inputs • These are Pb−Free Devices VCC OE I0c I1c Zc I0d I1d Zd 16 15 14 13 12 11 10 9 DATA SHEET .onsemi. 16 1 16 1 MARKING DIAGRAMS 16 SOIC−16 D SUFFIX CASE 751B 1 XXXXXXG AWLYWW TSSOP−16 DT SUFFIX CASE 948F 16 XXX XXX ALYWG G 1 XXX A WL, L Y WW, W G or G = Specific Device Code = Assembly Location = Wafer Lot = Year = Work Week = Pb−Free Package (Note: Microdot may be in either location) ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 7 of this data sheet. 12345678 S I0a I1a Za I0b I1b Zb GND Figure 1.
