Description
The IDT54/74FCT191 and IDT54/74FCT191A are reversible modulo-16 binary counters, featuring synchronous counting and asynchronous presetting and are built using an advanced dual metal CMOS technology.
Features
- IDT54/74FCT191 equivalent to FAST™ speed.
- IDT54/74FCT191A 35% faster than FAST.
- Equivalent to FAST output drive over full temperature
and voltage supply extremes.
- IOL = 48mA (commercial), 32mA (military).
- CMOS power levels (1mW typ. static).
- CMOS output level compatible.
- Substantially lower input current levels than FAST
(5µA max. ).
- JEDEC standard pinout for DIP, LCC and SOIC.
- Product available in Radiation Tolera.
