Nexperia USA Inc. 74AXP2T3407GSX

Overview

74AXP2T3407GSX from Nexperia is a dual-supply, dual-channel level-translating buffer IC featuring one push-pull output (1Y) and one open-drain output (2Y), with independent input (VCCI: 0.7–2.75 V) and output (VCCO: 1.2–5.5 V) supply rails. It enables bidirectional voltage translation between sub-1.2 V logic domains (e.g., 0.8 V I/O) and higher-voltage interfaces (e.g., 3.3 V or 5 V buses), supports partial power-down via IOFF, and operates across −40 °C to +85 °C.

For engineers reviewing the 74AXP2T3407GSX datasheet, 74AXP2T3407GSX pinout, 74AXP2T3407GSX application, or 74AXP2T3407GSX equivalent, this device serves as a low-power, Schmitt-triggered interface solution for mixed-voltage system interconnects-particularly where static/dynamic power minimization, rail-to-rail translation tolerance, and robust ESD immunity (HBM >2 kV) are critical selection criteria.

Technical Context

This device implements two independent buffer paths: Channel 1 (1A→1Y) uses a CMOS push-pull output referenced to VCCO, while Channel 2 (2A→2Y) employs an open-drain structure requiring external pull-up. Input thresholds follow JEDEC standards JESD8-12A.01 through JESD12-6, enabling interoperability across 0.8 V, 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5 V logic families.

The IOFF circuit actively disables both outputs when either supply is at 0 V, blocking backflow current during partial power-down. Schmitt-trigger inputs (typical hysteresis ≈0.2×VCCI) tolerate slow edges up to 200 ns/V, eliminating need for external RC filtering in noisy or high-impedance signal routing.

FAQ

Can 74AXP2T3407GSX translate between 0.8 V and 5 V logic levels?

Yes. With VCCI = 0.8 V and VCCO = 5.0 V, the device meets all recommended operating conditions: VIH/VIL thresholds remain valid per JESD8-12A.01, VOH reaches ≥3.7 V at IO = −12 mA, and VOL stays ≤0.8 V at IO = 12 mA - satisfying 5 V TTL and CMOS input requirements.

What is the maximum load capacitance supported on the 2Y open-drain output?

The 2Y output supports up to 50 pF load capacitance while maintaining tPLZ/tPZL ≤22.1 ns (VCCI = 0.75–0.85 V, VCCO = 1.2 V). For heavier loads, propagation delay increases linearly - e.g., +1.2 ns per 10 pF beyond 50 pF per Figure 6 in the datasheet.

Does the 74AXP2T3407GSX require external pull-up resistors on 2Y?

Yes. The 2Y terminal is open-drain and requires an external pull-up resistor to VCCO (or another compatible rail). Typical values range from 1 kΩ (for 50 MHz operation) to 10 kΩ (for low-power, <1 MHz applications), selected based on rise time and drive strength requirements.

How does the IOFF feature behave when only VCCI is powered?

When VCCI = 0 V and VCCO is active, the IOFF circuit disables both 1Y and 2Y outputs, limiting OFF-state leakage to ≤±0.5 µA. This prevents current backflow from VCCO into the unpowered input domain - critical for protecting 0.8 V cores during brown-out or controlled shutdown sequences.
