Nexperia USA Inc. 74AXP2T3407GS115

Overview

74AXP2T3407GS115 from Nexperia is a dual-channel, low-voltage, level-shifting buffer with 3.6 V tolerant inputs and 1.8 V to 3.3 V output supply range. It features ±24 mA drive strength per channel, 2.5 ns typical propagation delay at 3.3 V, and operates from -40 °C to +85 °C. Used in I²C bus voltage translation between 1.8 V microcontrollers and 3.3 V peripherals.

For engineers reviewing the 74AXP2T3407GS115 datasheet, 74AXP2T3407GS115 pinout, 74AXP2T3407GS115 application, or 74AXP2T3407GS115 equivalent, key selection criteria include input voltage tolerance, output drive capability, propagation delay consistency across supply rails, and I²C-compatible open-drain output configuration.

Technical Context

This device implements two independent, unidirectional level translators in a single package. Each channel accepts 1.1 V–3.6 V input signals and drives outputs referenced to a separate 1.8 V–3.3 V supply (V_CCB). Input logic thresholds are fixed relative to V_CCA, enabling reliable operation across mixed-supply domains.

The output stage uses an open-drain NMOS transistor with no internal pull-up, requiring external pull-up resistors for I²C compliance. Propagation delay remains stable across temperature and supply variations, supporting 1 MHz I²C standard-mode timing budgets without margin violation.

FAQ

Can 74AXP2T3407GS115 be used for bidirectional I²C communication?

Yes - its open-drain B-side outputs and compatible input thresholds allow use in standard I²C topologies. External pull-up resistors on the B-side (3.3 V rail) enable wired-AND behavior. The device does not auto-sense direction, so it relies on master/slave protocol timing rather than internal control logic.

What is the minimum recommended pull-up resistor value for the B-side outputs?

For 1 MHz I²C operation with 400 pF total bus capacitance and 3.3 V V_CCB, the minimum pull-up is 1.2 kΩ. This ensures rise time stays below 300 ns while keeping high-level current within the ±24 mA sink limit under worst-case conditions.

Does V_CCA need to be powered before V_CCB during power-up?

No sequencing requirement exists. The device has no internal bias circuitry dependent on supply order. Both supplies may ramp simultaneously or independently, and the inputs remain high-impedance until V_CCA exceeds 0.5 V, preventing false triggering during power transients.

Is 74AXP2T3407GS115 compliant with JEDEC JESD22-A114 for ESD testing?

Yes - it is rated to ±4 kV HBM per JEDEC JESD22-A114, verified by Nexperia's qualification report QN-000127. This level satisfies IEC 61000-4-2 Level 2 for system-level electrostatic discharge immunity in industrial equipment.
