74AXP1T125 Dual supply buffer/line driver; 3-state Rev. 1 -- 21 December 2015 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 (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 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 IOFF. The IOFF circuitry 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: 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 74AXP1T125 Nexperia Dual supply buffer/line driver; 3-state 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 VCCO IOFF circuitry provides partial power-down mode operation Multiple package options Specified from 40 C to +85 C 3.
