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_CCIand V_CCO).

A HIGH level at pin OE causes the output to assume a high-impedance OFF-state. The inputs

are referenced to V_CCIand the output is referenced to V_CCO. All inputs can be connected directly

to V_CCIor GND. V_CCIcan be supplied at any voltage between 0.7 V and 2.75 V and V_CCOcan 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_OFFcircuitry

disables the output, preventing the potentially damaging backflow current through the device when

it is powered down.

2. Features and benefits

•

Wide supply voltage range:

•

V_CCI: 0.7 V to 2.75 V

V_CCO: 1.2 V to 5.5 V

•

Low input capacitance; C_I= 0.6 pF (typical)

Low output capacitance; C_O= 1.8 pF (typical)

Low dynamic power consumption; C_PD= 0.4 pF at V_CCI= 1.2 V (typical)

Low dynamic power consumption; C_PD= 7.1 pF at V_CCO= 3.3 V (typical)

Low static power consumption; I_CCI= 0.5 μA (85 °C maximum)

Low static power consumption; I_CCO= 1.8 μA (85 °C maximum)

High noise immunity

Complies with JEDEC standard:

•

JESD8-12A.01 (1.1 V to 1.3 V; A, OE inputs)

JESD8-11A.01 (1.4 V to 1.6 V)

JESD8-7A (1.65 V to 1.95 V)

JESD8-5A.01 (2.3 V to 2.7 V)

JESD8-C (2.7 V to 3.6 V; Y output)

JESD12-6 (4.5 V to 5.5 V; Y output)

•

ESD protection:

•

HBM ANSI/ESDA/JEDEC JS-001 Class 2 exceeds 2 kV

CDM JESD22-C101E exceeds 1000 V

•

Latch-up performance exceeds 100 mA per JESD78D Class II

Inputs accept voltages up to 2.75 V

Low noise overshoot and undershoot < 10% of V_CCO

I_OFFcircuitry provides partial power-down mode operation

Multiple package options

Specified from -40 °C to +85 °C
