Nexperia USA Inc. 74LV1T32GWH

Overview

74LV1T32GWH from Nexperia is a single-supply, level-translating 2-input OR gate in TSSOP5 (SOT353-1) 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 computing and industrial controllers.

For engineers reviewing the 74LV1T32GWH datasheet, 74LV1T32GWH pinout, 74LV1T32GWH application, or 74LV1T32GWH equivalent, key selection criteria include input threshold compatibility (e.g., 1.8 V input at 3.3 V VCC), output drive capability (–5.5 mA / +5.5 mA at 3.3 V), 5 V input tolerance, and thermal performance in compact TSSOP5 packaging.

Technical Context

The 74LV1T32GWH implements a CMOS-based OR logic function with rail-referenced output levels tied directly to VCC, enabling seamless integration into heterogeneous voltage domains. Its input structure supports both up-translation (e.g., 1.8 V → 3.3 V) and down-translation (e.g., 5.0 V → 3.3 V), validated by 5 V-tolerant inputs and low-threshold input thresholds scalable with VCC.

Propagation delay is tightly specified across supply voltages (3.2 ns typical at 5.0 V/15 pF; 6.6 ns at 1.8 V/15 pF), and static characteristics-including VIH/VIL windows, VOH/VOL levels, and leakage (<±0.1 μA)-are guaranteed over full temperature range (–40 °C to +125 °C) and supply range (1.6 V to 5.5 V).

FAQ

Can 74LV1T32GWH translate 5 V inputs while operating at VCC = 1.8 V?

Yes. The device features 5 V-tolerant inputs, allowing safe reception of 5 V logic signals even when powered from 1.8 V. Output levels will be 1.8 V-referenced (VOH ≥ 1.45 V, VOL ≤ 0.25 V), enabling direct connection to 1.8 V receivers without additional components.

What is the maximum capacitive load the 74LV1T32GWH can drive at 3.3 V while maintaining 50 MHz operation?

At VCC = 3.3 V, the device supports CL = 15 pF with tpd = 3.9 ns (typical), enabling reliable 50 MHz toggle operation. With CL = 30 pF, tpd increases to 4.4 ns, still supporting >50 MHz in most synchronous applications-verified per Table 10 test data under 3 V input transition rate.

Does 74LV1T32GWH require external pull-up or pull-down resistors on unused inputs?

No. Unused inputs must be terminated to VCC or GND to prevent floating states and excessive ICC. The device has no internal termination; however, its low input leakage (<±0.1 μA) allows use of high-value resistors (e.g., 100 kΩ) if needed for board-level flexibility.

Is the TSSOP5 (SOT353-1) package of 74LV1T32GWH compatible with reflow soldering per J-STD-020?

Yes. The SOT353-1 package is qualified for standard lead-free reflow profiles (peak 260 °C, 60 s max above 217 °C). Thermal derating begins at 74 °C (3.3 mW/K), so PCB layout must ensure adequate copper pour and thermal vias for continuous 125 °C ambient operation.
