Hex Schmitt-Trigger Inverter Logic IC in bare die form

Description
The 54AC14 Hex Schmitt-Trigger Inverter is fabricated
using a 1.5μm 5V CMOS process with the same high
speed performance of LSTTL combined with CMOS low
power consumption. The device performs the Boolean
function Y = Ᾱ in positive logic. Device inputs are
compatible with Standard CMOS outputs; with pull-up
resistors, they are compatible with LSTTL outputs.
Schmitt-Trigger inputs transform slow input rise and fall
times into sharply defined jitter-free output signals. Due to
the hysteresis voltage of the Schmitt trigger, the 54AC14 is
useful in noisy environments.

Features:
Outputs Sink/Source 24mA
Low Input Current: 1μA
Outputs directly interface CMOS, NMOS and TTL
Operating Voltage Range: 2V to 6V
CMOS High Noise Immunity
Function compatible with 54HC14 or 54LS14
Full Military Temperature Range.
