Each device has an active enable G and a direction control input, DIR.

When DIR is high, data flows from the A inputs to the B outputs.

When DIR is low, data flows from the B inputs to the A outputs.

High Speed Operation: tpd = 12 ns typ (CL = 50 pF).
High Output Current: Fanout of 15 LSTTL Loads.
Wide Operating Voltage: VCC = 2 to 6 V.
Low Input Current: 1 µA max.
Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C).
