IDT74AHCT191 - High Speed CMOS Up-Down Binary Counter

Description

The IDT54174AHCT191 is a reversible modul0-16 binary counter, featuring synchronous counting and asynchronous presetting, built using advanced CEMOS'

, a dual metal CMOS tEl6:hnology.

The preset feature allows the IDT54/74AHCT191 to be used in programmable dividers.

Features

  • Equivalent to ALS speeds and output drive over full temperature and voltage supply extremes.
  • IOL = 14mA over full military temperature range.
  • CMOS power levels (5!J. W typo static).
  • Both CMOS and TTL output compatible.
  • Substantially lower input current levels than ALS (5!J. max. ).
  • 100% product assurance screening to MIL-STD-883, Class B is available.
  • JEDEC standard pinout for DIP and LCC.
