Description
The IDT54/74FCT139/A/C are dual 1-of-4 decoders built using an advanced dual metal CMOS technology..
Features
- IDT54/74FCT139 equivalent to FAST™ speed.
- IDT54/74FCT139A 35% faster than FAST.
- IDT54/74FCT139C 45% faster than FAST.
- Equivalent to FAST output drive over full temperature
and voltage supply extremes.
- IOL = 48mA (commercial) and 32mA (military).
- CMOS power levels (1mW typ. static).
- TTL input and output level compatible.
- CMOS output level compatible.
- Substantially lower input current levels than FAST
(5µA max. ).
