com MC54/74F138 1-OF-8 DECODER/ DEMULTIPLEXER The MC54/74F138 is a high speed 1-of-8 Decoder/Demultiplexer.
This device is ideally suited for high speed bipolar memory chip select address decoding.
The multiple input enables allow parallel expansion to a 1-of-24 decoder using just three F138 devices or to a 1-of-32 decoder using four F138s and one inverter.
• Demultiplexing Capability • Multiple Input Enable for Easy Expansion • Active Low Mutually Exclusive Outputs • Input Clamp Diodes Limit High-Speed Termination Effects CONNECTION DIAGRAM DIP (TOP VIEW) VCC 16 O0 15 O1 14 O2 13 O3 12 O4 11 O5 10 O6 9 16 1 1-OF-8 DECODER/ DEMULTIPLEXER FAST™ SHOTTKY TTL J SUFFIX CERAMIC CASE 620-09 16 N SUFFIX PLASTIC CASE 648-08 1 1 A0 2 A1 3 A2 4 E1 5 E2 6 E3 7 8 DataShee ODataSheet4U.
