Nexperia USA Inc. 74AXP1T57GSX

Overview

74AXP1T57 from Nexperia is a dual-supply configurable logic gate with Schmitt-trigger inputs, three inputs (A/B/C), one output (Y), and independent input/output supply rails (VCCI: 0.7–2.75 V; VCCO: 1.2–5.5 V). It supports seven logic functions (AND, OR, NAND, NOR, XNOR, inverter, buffer) via pin strapping and enables bidirectional voltage level translation between disparate logic domains. Used in mixed-voltage I/O interfacing on industrial microcontroller peripherals.

For engineers reviewing the 74AXP1T57 datasheet, 74AXP1T57 pinout, 74AXP1T57 application, or 74AXP1T57 equivalent, key selection criteria include dual-rail voltage translation capability, Schmitt-trigger noise immunity, IOFF partial power-down support, and ultra-low static current (<1 μA at 85 °C) for battery-sensitive systems.

Technical Context

The device implements a configurable logic cell where A, B, and C inputs are referenced to VCCI and drive Y referenced to VCCO, enabling true level-shifting without external biasing. Its Schmitt-trigger inputs provide hysteresis (0.2–1.0 V) across VCCI ranges, ensuring robust noise rejection in noisy environments.

IOFF circuitry disables the output when either supply is near 0 V, blocking backflow current during partial power-down-critical for hot-swap and power-gated subsystems. The logic function is determined by hardwiring A/B/C to VCCI or GND per Table 5, eliminating configuration registers or serial interface overhead.

FAQ

What logic functions can the 74AXP1T57 implement, and how is configuration performed?

The 74AXP1T57 supports AND, OR, NAND, NOR, XNOR, inverter, and buffer functions. Configuration is achieved by hardwiring inputs A, B, and C to VCCI or GND according to Table 5 in the datasheet-no programming interface or external clock is required. Each function corresponds to a specific pin-strapping pattern, making it a one-time hardware setup.

Does the 74AXP1T57 support true bidirectional level translation?

No-the 74AXP1T57 performs unidirectional level translation only: inputs are referenced to VCCI and the output to VCCO. Signal flow is strictly A/B/C → Y. For bidirectional translation (e.g., I²C), a dedicated bus buffer like the NXB0104 is required.

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

When VCCI = 0 V and VCCO is active, the IOFF circuit forces Y into high-impedance state regardless of input states, preventing backfeed into the unpowered input domain. This behavior is verified in Table 4 (function table) row "GND / VCCO" where Y = Z (high-Z) for all A/B/C combinations.

Can the 74AXP1T57 operate with VCCI = 1.2 V and VCCO = 1.8 V simultaneously?

Yes-this combination is fully supported within the recommended operating conditions (VCCI: 0.7–2.75 V; VCCO: 1.2–5.5 V). Propagation delay is 7.9–12.0 ns (typical) and output drive strength meets VOH ≥ 1.62 V / VOL ≤ 0.45 V at IO = ±4.5 mA, enabling reliable interfacing between 1.2 V and 1.8 V logic domains.
