description/ordering information (continued)
During power up, Q outputs are in the low state, and Q outputs are in the high state. The outputs are glitch free,
without applying a reset pulse.
These devices are fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the
outputs, preventing damaging current backflow through the devices when they are powered down.
Pin assignments for these devices are identical to those of the ’AHC123A and ’AHCT123A devices for
interchangeability, when allowed.
