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 pi ns
(VCCI and VCCO). A HIGH level at pin OE causes the output to assume a high-impedance
OFF-state. The inputs are referenced to VCCI and the output is referenced to VCCO. All
inputs can be connected directly to VCCI or GND. VCCI can be supplied at any voltage
between 0.7 V and 2.75 V and VCCO can be supplied at any vo ltage between 1.2 V and
5.5 V. This feature allows voltage level translation.
Schmitt-trigger action at all input s makes the circuit tolerant of slower input rise and fall
times.
This device ensures very low static and dynamic power con su mption across the entire
supply range and is fully sp ecified for partial power down applications using IOFF. The I OFF
circuitry disabl es the output, preventing th e potentially damaging backflow cur rent through
the device when it is powe red down.
2. Features and benefits
Wide supply voltage range:
VCCI: 0.7 V to 2.75 V
VCCO: 1.2 V to 5.5 V
Low input capacitance; CI = 0.6 pF (typical)
Low output capacitance; CO = 1.8 pF (typical)
Low dynamic power consumption; CPD = 0.4 pF at VCCI = 1.2 V (typical)
Low dynamic power consumption; CPD = 7.1 pF at VCCO = 3.3 V (typical)
Low static power consumption; ICCI = 0.5 A (85 C maximum)
Low static power consumption; ICCO = 1.8 A (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
