The ’HCT139 devices are designed for highperformance memory-decoding or data-routing applications requiring very short propagation delay times.

Operating voltage range of 4.5 V to 5.5 V.
Outputs can drive up to 10 LSTTL loads.
Low power consumption, 80-µA max ICC.
Typical tpd = 10 ns.
±4-mA output drive at 5 V.
Low input current of 1 µA max.
Inputs are TTL-voltage compatible.
Designed specifically for high-speed memory decoders and data-transmission systems.
Incorporate two enable inputs to simplify cascading and/or data reception 2.
