74AXP1T32
Dual supply 2-input OR gate
Rev. 2 — 22 March 2019 Product data sheet
1. General description
The 74AXP1T32 is a dual supply 2-input OR gate. It features two inputs (A, B), an output (Y) and
dual supply pins (V
CCI
and V
CCO
). The inputs are referenced to V
CCI
and the output is referenced
to V
CCO
. All inputs can be connected directly to V
CCI
or GND. V
CCI
can be supplied at any voltage
between 0.7 V and 2.75 V. V
CCO
can be supplied at any voltage between 1.2 V and 5.5 V. This
feature allows voltage level translation.
Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.
This device ensures very low static and dynamic power consumption across the entire supply
range and is fully specified for partial power down applications using I
OFF
. The I
OFF
circuitry
disables the output, preventing the potentially damaging backflow current through the device when
it is powered down.
