This multiplexer

both true (Y) and complement (W) outputs as well as a strobe input. The strobe must be at a low logic level to enable this device. When the strobe input is high, both outputs are in the high impedance state. When enabled, address information on the data select inputs determines which data input is routed to the Y and W outputs. Features.
High Speed Operation: tpd (A, B, C to Y) = 20 ns typ (C L = 50 pF) High Output Current: Fanout of 10 LSTTL Loa.
