Nexperia USA Inc. 74LV1T32GXH

Overview

74LV1T32GXH from Nexperia is a single-supply, level-translating 2-input OR gate in X2SON5 (SOT1226-3) package, supporting bidirectional voltage translation between 1.2 V–5.0 V logic domains. It features 5 V-tolerant inputs, operates from -40 °C to +125 °C, and delivers propagation delays as low as 3.2 ns at 5.0 V/15 pF - enabling inter-voltage-domain signal routing in portable power-constrained systems.

For engineers reviewing the 74LV1T32GXH datasheet, 74LV1T32GXH pinout, 74LV1T32GXH application, or 74LV1T32GXH equivalent, key selection criteria include input threshold compatibility across VCC = 1.65–5.5 V, guaranteed 5 V input tolerance with VCC as low as 1.8 V, output drive capability up to ±8 mA, and thermal performance in 0.8 × 0.8 mm X2SON5 for high-density PCB layouts.

Technical Context

The 74LV1T32GXH implements a CMOS-based OR logic function with rail-referenced outputs: Y = A OR B. Its input stage uses low-threshold MOSFETs enabling reliable detection of 1.2 V inputs when VCC = 1.8 V and 3.3 V inputs when VCC = 2.5 V - supporting both up-translation (e.g., 1.8 V → 3.3 V) and down-translation (e.g., 5.0 V → 3.3 V).

Input clamping diodes and ESD protection structures meet HBM >2000 V and CDM >1000 V per JS-001/JS-002. The device draws only 1 μA typical ICC per input at VCC = 1.8–5.0 V and maintains functional operation under ±25 mA output sink/source current limits per IEC 60134 limiting values.

FAQ

What is the maximum input voltage the 74LV1T32GXH can tolerate when VCC = 1.8 V?

The 74LV1T32GXH supports input voltages up to 7.0 V regardless of VCC setting, per Absolute Maximum Ratings Table 5. At VCC = 1.8 V, this enables safe interfacing with 3.3 V or 5.0 V signals without external clamping - confirmed by 5 V tolerance specification in Section 2 and VI limit of -0.5 V to +7.0 V.

Does the 74LV1T32GXH require pull-up or pull-down resistors on unused inputs?

No external resistors are required. Unused inputs must be tied to VCC or GND to prevent floating states, as specified in Section 10 Recommended Operating Conditions. The device has no internal weak pull-ups or pull-downs; leaving an input unconnected risks undefined logic states and increased ICC due to input stage instability.

How does the X2SON5 (SOT1226-3) package affect thermal performance compared to TSSOP5?

The X2SON5 package provides superior thermal resistance: Ptot derates at 3.0 mW/K above 67 °C, versus 3.3 mW/K above 74 °C for TSSOP5. Its 0.32 mm height and thermal pad allow direct PCB copper contact, reducing θJA by ~15 °C/W over TSSOP5 - critical for sustained operation in compact, sealed enclosures.

Can the 74LV1T32GXH perform OR logic with mixed-voltage inputs (e.g., 1.8 V on A, 3.3 V on B)?

Yes. Both inputs are independently 5 V tolerant and threshold-defined relative to VCC, not to each other. With VCC = 3.3 V, a 1.8 V signal on A and 3.3 V signal on B will both register as valid HIGH per VIH = 0.80 V min (Table 7), producing correct OR output - verified by functional table (Section 8) and up/down translation specifications (Section 1).
