Nexperia USA Inc. 74AXP1T57DC-Q100H

Overview

74AXP1T57DC-Q100 from Nexperia is an automotive-grade dual-supply configurable logic gate with Schmitt-trigger inputs, supporting AND/OR/NAND/NOR/XNOR/inverter/buffer functions via pin-strapping of A/B/C inputs. It operates with independent input supply (VCCI: 0.7–2.75 V) and output supply (VCCO: 1.2–5.5 V), enabling bidirectional voltage level translation in mixed-voltage automotive subsystems such as body control modules and sensor interfaces.

For engineers reviewing the 74AXP1T57DC-Q100 datasheet, 74AXP1T57DC-Q100 pinout, 74AXP1T57DC-Q100 application, or 74AXP1T57DC-Q100 equivalent, this device delivers verified IOFF-enabled partial power-down operation, sub-1 ns transition times, <0.6 pF input capacitance, and AEC-Q100 Grade 1 qualification for under-hood environments up to +125 °C ambient.

Technical Context

This configurable gate uses Schmitt-trigger inputs referenced to VCCI and a CMOS output stage referenced to VCCO, allowing robust noise immunity and rail-to-rail logic compatibility across two independent voltage domains. Its function selection is determined solely by static DC levels applied to inputs A, B, and C - no clock, configuration register, or external programming is required.

The IOFF circuit disables the output when either supply is at 0 V, preventing backflow current during power sequencing. Propagation delay ranges from 7.2 ns (VCCI=2.5 V, VCCO=5.0 V) to 225 ns (low-VCCI, high-temperature, worst-case load), with hysteresis (VH) from 0.2 V to 1.0 V ensuring reliable switching in noisy automotive environments.

FAQ

Can 74AXP1T57DC-Q100 operate with VCCI = 0.7 V and VCCO = 5.5 V simultaneously?

Yes. The device is fully characterized across the entire VCCI (0.7–2.75 V) and VCCO (1.2–5.5 V) ranges, including corner combinations. At VCCI = 0.7 V, input thresholds scale to ~0.21–0.56 V (VT−/VT+), ensuring valid logic recognition of 0.7 V-referenced signals while driving a full 5.5 V output swing. Propagation delay increases to 225 ns at −40 °C to +125 °C extremes but remains functional.

How is logic function selected without programming or configuration registers?

Function selection is purely static and determined by DC voltage levels applied to pins A, B, and C. For example, tying A=HIGH, B=LOW, C=LOW configures the device as a 2-input NOR gate; A=LOW, B=HIGH, C=HIGH yields a 2-input AND. No clock, serial interface, or internal state machine is involved - behavior is combinatorial and immediate upon power stabilization.

Does the IOFF feature require external pull-up/down resistors on Y during power-down?

No. When either VCCI or VCCO is at 0 V, the internal IOFF circuit forces Y into a high-impedance state with leakage ≤±2.0 μA at +125 °C. External resistors are unnecessary for isolation - the output floats safely without sourcing or sinking current, protecting downstream devices during asymmetric power sequencing.

What is the maximum capacitive load the Y output can drive while maintaining specified tpd and tt?

The datasheet specifies performance up to CL = 120 pF (see Fig. 14–19). At VCCO = 3.3 V and Tamb = 25 °C, tpd remains ≤10.2 ns and tt ≤1.0 ns for CL ≤120 pF. Driving >120 pF increases delay nonlinearly and may degrade edge monotonicity; for heavier loads, add a local buffer or reduce trace length/capacitance.
