IDT74FCT191A - FAST CMOS UP/DOWN BINARY COUNTER

Download the IDT74FCT191A datasheet PDF. This datasheet also covers the IDT74FCT191 variant, as both devices belong to the same fast cmos up/down binary counter family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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.
