Nexperia USA Inc. 74LV1T00GWH

Overview

74LV1T00GWH from Nexperia is a single-supply, level-translating 2-input NAND gate IC designed for voltage domain bridging in mixed-voltage digital systems. It supports up translation (e.g., 1.8 V input → 3.3 V output at VCC = 3.3 V) and down translation (e.g., 5.0 V input → 3.3 V output at VCC = 3.3 V), features 5 V tolerant inputs, operates across 1.6 V to 5.5 V supply range, and is qualified from –40 °C to +125 °C - enabling use in industrial controllers and portable power-constrained interfaces.

For engineers reviewing the 74LV1T00GWH datasheet, 74LV1T00GWH pinout, 74LV1T00GWH application, or 74LV1T00GWH equivalent, key selection criteria include its single-gate translating function, 5-pin TSSOP5 (SOT353-1) package, guaranteed propagation delay ≤12.3 ns (VCC = 1.8 V, CL = 30 pF), ±25 mA output drive, and IEC-compliant logic symbol compliance.

Technical Context

This device implements a standard NAND Boolean function (Y = NOT(A AND B)) with input thresholds dynamically referenced to VCC, enabling reliable switching across 1.6 V–5.5 V supply voltages. Its 5 V tolerant inputs allow direct interfacing with legacy 5 V logic while driving modern low-voltage CMOS loads (1.8 V/2.5 V/3.3 V).

The architecture eliminates external level-shifting components by integrating rail-to-rail input hysteresis and output swing referenced strictly to VCC. Static characteristics are specified across three temperature ranges (–40 °C to +125 °C), and dynamic performance includes propagation delays characterized at multiple VCC/CL combinations, supporting clock rates up to 50 MHz at 3.3 V.

FAQ

Can 74LV1T00GWH translate 5 V inputs to 1.8 V outputs?

No. While the inputs tolerate 5 V, the output swing is referenced solely to VCC. To generate a 1.8 V output, VCC must be set to 1.8 V - but at that voltage, the device does not guarantee 5 V input tolerance per datasheet Table 5 (VI max = VCC + 0.5 V = 2.3 V). Therefore, 5 V → 1.8 V translation is electrically unsafe and unsupported.

What is the minimum VCC required for reliable operation with 1.8 V inputs?

The minimum recommended VCC is 1.6 V per Table 6. At VCC = 1.6 V, VIH is guaranteed ≥0.94 V (for VCC = 1.65–1.8 V), ensuring recognition of 1.8 V inputs as HIGH. Operation below 1.6 V violates recommended conditions and risks incorrect logic interpretation or increased propagation delay.

Does 74LV1T00GWH support open-drain or push-pull output configuration?

It features a standard CMOS push-pull output stage (not open-drain). The Y pin actively drives HIGH to VCC and LOW to GND, with symmetrical ±25 mA capability. External pull-ups are unnecessary and may cause contention if VCC differs from the pull-up rail voltage.

How does thermal derating apply to the SOT353-1 package?

For SOT353-1 (TSSOP5), total power dissipation (Ptot) is rated at 250 mW up to 74 °C ambient. Above 74 °C, Ptot derates linearly at 3.3 mW/K - meaning at 100 °C ambient, maximum allowable power drops to 250 mW − (100−74) × 3.3 mW = 164.2 mW. Layout must ensure adequate copper area and airflow to maintain junction temperature within limits.
