Product Summary
The 74LS139 is a schottky-clamped TTL MSI circuit designed to be used in high-performance memory-decoding or data-routing applicatiosn requiring very short propagation delay times. In high-performance memory systems, the decoder 74LS139 can be used to minimize the effects of system decoding.
Parametrics
74LS139 absolute maximum ratings: (1)supply voltage, VCC: 7V; (2)input voltage: 7V; (3)operating free-air temperature range: -55 to 125℃; (4)storage temperature range: -65 to 150℃.
Features
74LS139 features: (1)designed specifically for high-speed: memory decoders; data transmission sytems; (2)two fully independent 2- to 4-line decoders/demultiplexers; (3)schottky clamped for high performance.
