Nexperia USA Inc. 74LV1T32GVH

Overview

74LV1T32GV from Nexperia is a single-supply, level-translating 2-input OR gate in SC-74A (SOT753) package, supporting bidirectional voltage translation between 1.2 V–5.0 V logic domains. It delivers 3.9 ns propagation delay at 3.3 V/15 pF, 5 V-tolerant inputs, and operates across –40 °C to +125 °C. It enables logic-level bridging in mixed-voltage I/O interfaces of portable microcontroller subsystems.

For engineers reviewing the 74LV1T32GV datasheet, 74LV1T32GV pinout, 74LV1T32GV application, or 74LV1T32GV equivalent, this page provides verified pin functions, real-world translation use cases, static/dynamic electrical boundaries, thermal derating behavior per SOT753, and validated alternative parts for voltage-level interface design.

Technical Context

The device implements a single CMOS OR gate with input thresholds dynamically scaled to VCC, enabling up-translation (e.g., 1.8 V inputs → 3.3 V outputs at VCC = 3.3 V) and down-translation (e.g., 5.0 V inputs → 3.3 V outputs at VCC = 3.3 V). Its 5 V-tolerant inputs operate independently of VCC, allowing safe interfacing with higher-voltage controllers.

Propagation delay is load- and supply-dependent: 3.9 ns (typ.) at VCC = 3.3 V/CL = 15 pF, degrading to 6.4 ns (max) over temperature; input capacitance is 1.5–10 pF, output capacitance is 2.5 pF - both critical for timing closure in high-speed I/O buffers.

FAQ

Can 74LV1T32GV translate 5 V inputs to 1.8 V outputs?

Yes. With VCC = 1.8 V, the device supports 5 V → 1.8 V down-translation: inputs tolerate up to 7.0 V, and the output swings rail-to-rail between GND and 1.8 V. Static characteristics confirm VOH ≥1.45 V and VOL ≤0.25 V at IO = ±2 mA, meeting 1.8 V CMOS logic thresholds.

What is the maximum capacitive load the output can drive reliably?

The output is characterized up to 30 pF load capacitance. At VCC = 3.3 V and CL = 30 pF, tpd remains ≤7.3 ns (max) across –40 °C to +125 °C. Driving >30 pF risks violating setup/hold timing in high-speed interfaces and may exceed the 25 mA absolute max output current rating.

Does 74LV1T32GV require external pull-up or pull-down resistors?

No. The device has no internal weak pull-ups or pull-downs. Inputs are standard CMOS with ±0.1 μA leakage; unused inputs must be externally tied to VCC or GND to prevent floating states and undefined logic behavior - confirmed by functional table and static input current specs.

How does thermal derating work for the SOT753 package?

For SOT753 (SC-74A), total power dissipation derates linearly at 3.8 mW/K above +85 °C ambient. At +105 °C, Ptot drops to 250 mW − (20 K × 3.8 mW/K) = 174 mW. This is defined in Table 5 Note [4] and constrains continuous output current in high-temperature industrial deployments.
