Nexperia USA Inc. 74LV1T02GXH

Overview

74LV1T02GXH from Nexperia is a single-supply, level-translating 2-input NOR gate in X2SON5 (SOT1226-3) package. It performs bidirectional voltage translation between 1.2 V–5.0 V logic domains, supports 5 V tolerant inputs, operates from −40 °C to +125 °C, and delivers CMOS-compatible output levels referenced to VCC. It enables interface bridging between mixed-voltage subsystems in portable and industrial controllers.

For engineers reviewing the 74LV1T02GXH datasheet, 74LV1T02GXH pinout, 74LV1T02GXH application, or 74LV1T02GXH equivalent, this page provides verified functional behavior, validated level translation ranges, confirmed thermal and ESD specifications, and real-world use cases for voltage-domain interfacing in space-constrained designs.

Technical Context

The device implements a true NOR logic function with dual input pins (A, B) and one output (Y), where Y = NOT(A OR B). Its internal circuitry uses low-threshold MOSFETs enabling reliable 1.8 V input detection at VCC = 3.3 V (up-translation) and 5 V tolerant inputs supporting down-translation (e.g., 3.3 V input → 2.5 V output at VCC = 2.5 V).

All I/O levels are referenced to VCC, allowing output swing from 0 V to VCC across 1.6 V–5.5 V supply range. Propagation delay is 3.2 ns (typ.) at VCC = 5.0 V and CL = 15 pF, with input capacitance ≤10 pF and power dissipation capacitance of 12.0 pF at 5.0 V.

FAQ

What voltage levels can 74LV1T02GXH translate between?

The 74LV1T02GXH supports up-translation (e.g., 1.8 V inputs at VCC = 3.3 V) and down-translation (e.g., 3.3 V or 5 V inputs at VCC = 2.5 V or 3.3 V). Confirmed ranges include 1.2 V→1.8 V, 1.8 V→3.3 V, 3.3 V→1.8 V, 3.3 V→2.5 V, 5.0 V→3.3 V, and 3.3 V→5.0 V, all with rail-to-rail CMOS output referenced to VCC.

Is 74LV1T02GXH pin-compatible with other 5-pin logic packages?

No - the 74LV1T02GXH uses the X2SON5 (SOT1226-3) package with bottom-terminal layout and no leads, differing physically from TSSOP5 (SOT353-1) and SC-74A (SOT753). Pin functions (A, B, GND, Y, VCC) match electrically, but soldering, rework, and PCB footprint are not interchangeable.

Does 74LV1T02GXH require external pull-up or pull-down resistors?

No - the device has no internal weak pull-ups or pull-downs, and its inputs are CMOS with ≤0.1 μA leakage. External resistors are only needed if specific idle-state biasing is required by system logic; unused inputs should be tied to VCC or GND per standard CMOS practice.

How does thermal performance compare across 74LV1T02 package variants?

The X2SON5 (74LV1T02GXH) package has a thermal resistance of 3.0 mW/K above 67 °C, lower than TSSOP5 (3.3 mW/K above 74 °C) and SC-74A (3.8 mW/K above 85 °C). This enables higher sustained power density in thermally constrained layouts, verified per datasheet derating curves.
