General description

The 74AXP1T34 is a dual supply translating buffer. It features one input (A), an output (Y)

and dual supply pins (VCCI and VCCO). 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.

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 input)

 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
