Nexperia USA Inc. 74LV1T02GWH

Overview

74LV1T02GWH from Nexperia is a single-supply, level-translating 2-input NOR gate in TSSOP5 (SOT353-1) 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 interface bridging between mixed-voltage microcontrollers and peripherals in portable and industrial systems.

For engineers reviewing the 74LV1T02GWH datasheet, 74LV1T02GWH pinout, 74LV1T02GWH application, or 74LV1T02GWH equivalent, key selection criteria include its single-supply level translation capability, 5 V input tolerance, guaranteed operation across 1.6 V–5.5 V VCC, -40 °C to +125 °C temperature range, and TSSOP5 footprint compatibility with space-constrained PCB layouts.

Technical Context

This device implements a true NOR logic function (Y = NOT(A OR B)) with input thresholds dynamically scaled to VCC, enabling reliable up-translation (e.g., 1.8 V inputs → 3.3 V outputs at VCC = 3.3 V) and down-translation (e.g., 3.3 V inputs → 1.8 V outputs at VCC = 1.8 V). Its 5 V-tolerant inputs allow direct connection to legacy 5 V buses without external resistors.

Static performance is specified across three temperature ranges (-40 °C to +125 °C inclusive), with VOH ≥ 1.28 V at VCC = 1.65 V/IO = -2 mA and VOL ≤ 0.35 V at VCC = 4.5 V/IO = 8 mA. Dynamic behavior includes CL-dependent propagation delay (3.2–12.2 ns) and input capacitance ≤ 10 pF, supporting >50 MHz operation at 3.3 V/15 pF.

FAQ

What is the maximum input voltage the 74LV1T02GWH can safely accept?

The 74LV1T02GWH supports absolute maximum input voltage of +7.0 V per IEC 60134, with 5 V tolerance explicitly guaranteed under normal operating conditions. This allows direct connection to 5 V buses without external protection, provided VCC remains within 1.6–5.5 V and input current stays below ±20 mA.

Can the 74LV1T02GWH translate from 3.3 V inputs to 1.8 V outputs?

Yes - when VCC = 1.8 V, the device performs level down-translation: 3.3 V inputs are accepted (due to 5 V tolerance), and the output swings between 0 V and ~1.8 V. The datasheet confirms 3.3 V to 1.8 V translation is supported, with VOH ≥ 1.28 V and VOL ≤ 0.25 V at IO = ±2 mA.

Is the 74LV1T02GWH pin-compatible with other single-gate NOR packages?

No - the 74LV1T02GWH uses a proprietary 5-pin TSSOP5 (SOT353-1) pinout (B-A-GND-Y-VCC). It is not pin-compatible with SC-74A (SOT753) or X2SON5 (SOT1226-3) variants of the same logic function, nor with industry-standard 5-pin SOT-23 or SC-70 packages due to differing pin assignments and thermal pad configurations.

Does the 74LV1T02GWH require external pull-up or pull-down resistors?

No - the device has CMOS inputs with ±0.1 μA leakage current and does not require external biasing. Inputs float to undefined states if left unconnected, so system-level pull-ups/pull-downs must be applied per design intent; the IC itself contains no internal resistors and operates correctly with driven inputs only.
