( DataSheet : .. ) MC74AC258 MC74ACT258 Quad 2ĆInput Multiplexer with 3ĆState Outputs The MC74AC258/74ACT258 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 the plement (inverted) form. The outputs may be switched to a high impedance state with a HIGH on the mon Output Enable (OE) input, allowing the outputs to interface directly with bus-oriented systems. - - - - Multiplexer Expansion by Tying Outputs Together Inverting 3-State Outputs Outputs Source/Sink 24 mA ′ACT258 Has TTL patible Inputs VCC 16 OE 15 I0c 14 I1c 13 Zc 12 I0d...
