Nexperia USA Inc. 74AXP1T14GWH

Overview

74AXP1T14GWH from Nexperia is a dual-supply Schmitt trigger inverter with independent input (VCCI) and output (VCCO) supply rails, enabling bidirectional voltage level translation between 0.7 V–2.75 V and 1.2 V–5.5 V domains. It features one logic input (A), one inverted output (Y), IOFF partial power-down protection, and operates across –40 °C to +85 °C. Used in mixed-voltage I/O bridging for low-power microcontrollers and sensor interfaces.

For engineers reviewing the 74AXP1T14GWH datasheet, 74AXP1T14GWH pinout, 74AXP1T14GWH application, or 74AXP1T14GWH equivalent, this device is selected for its ultra-low static current (≤0.5 μA at 85 °C), sub-1 ns transition time, Schmitt-trigger noise immunity, and JEDEC-compliant voltage translation across five standard logic families (JESD8-12A.01 through JESD12-6).

Technical Context

The 74AXP1T14GWH implements a single-channel Schmitt-trigger inverter with physically isolated VCCI and VCCO supplies-input threshold voltages (VT+, VT−) scale with VCCI, while output swing and drive strength are referenced solely to VCCO. Its IOFF circuit actively disables Y when either supply is near 0 V, blocking backflow current during partial power-down sequences.

It supports dynamic operation across 12 distinct VCCI/VCCO combinations (e.g., 1.2 V → 3.3 V, 1.8 V → 5.0 V), with propagation delay ranging from 1.9 ns (VCCI = 2.5 V, VCCO = 5.0 V) to 148 ns (low-VCCI, wide-temp), and hysteresis (VH) tightly controlled from 0.2 V to 1.0 V depending on VCCI.

FAQ

What is the minimum VCCI voltage required for guaranteed logic-level recognition?

The device is specified down to 0.7 V VCCI, with valid VIH/VIL thresholds defined at 0.3×VCCI (min) and 0.7×VCCI (max) for VCCI = 1.1 V–1.95 V. At 0.75 V VCCI, VIH is guaranteed ≥0.23 V and VIL ≤0.53 V per Table 7, enabling reliable operation with sub-1 V logic families such as certain ultra-low-power MCUs.

Can VCCI and VCCO be powered from the same rail?

Yes - VCCI and VCCO may be tied together within their overlapping range (1.2 V–2.75 V). Doing so configures the device as a standard single-supply Schmitt inverter with enhanced noise immunity and IOFF protection, retaining all static/dynamic performance specs including 0.6 pF input capacitance and sub-2 ns propagation delay.

Does the 74AXP1T14GWH support hot insertion or live board swapping?

Yes - the IOFF circuit activates when either VCCI or VCCO falls below ~0.1 V, forcing Y into high-impedance state and limiting backflow current to <±0.5 μA. This meets IEC 61000-4-2 Level 4 ESD robustness (≥2 kV HBM) and enables safe hot-plug operation in modular industrial backplanes and field-replaceable units.

How does hysteresis vary with VCCI, and why does it matter for switch debouncing?

Hysteresis (VH) scales with VCCI: 0.06×VCCI (min) to 0.5×VCCI (max) at low VCCI, widening to 0.2 V–1.0 V at 2.3–2.7 V. This ensures consistent noise margin regardless of input supply - e.g., at 1.2 V VCCI, VH ≈ 0.3 V rejects typical switch bounce (100–300 mV), while at 2.5 V VCCI, VH ≈ 0.8 V handles higher-amplitude transients in automotive environments.
