74AXP1T125
Dual supply buffer/line driver; 3-state
Rev. 2 — 22 March 2019 Product data sheet
1. General description
The 74AXP1T125 is a dual supply non-inverting buffer/line driver with 3-state output. It features
one input (A), an output (Y), an output enable input (OE) and dual supply pins (V
CCI
and V
CCO
).
A HIGH level at pin OE causes the output to assume a high-impedance OFF-state. 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 and 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.
