Nexperia USA Inc. 74LVC2G02DP-Q100H

Overview

74LVC2G02DP-Q100 from Nexperia is a dual 2-input NOR gate logic IC qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C), featuring 1.65 V to 5.5 V supply operation, ±24 mA output drive at V_CC = 3.0 V, and IOFF partial power-down protection. It serves as a level-translating logic buffer in automotive body control modules, enabling interoperability between 3.3 V microcontrollers and 5 V sensor interfaces.

For engineers reviewing the 74LVC2G02DP-Q100 datasheet, 74LVC2G02DP-Q100 pinout, 74LVC2G02DP-Q100 application, or 74LVC2G02DP-Q100 equivalent, key selection criteria include its Schmitt-trigger input tolerance for slow-rising signals, 5 V-tolerant I/O, −40 °C to +125 °C automotive temperature range, and TSSOP8 (SOT505-2) package compatibility with high-density PCB layouts.

Technical Context

This device implements two independent CMOS NOR gates with Schmitt-trigger inputs, enabling robust noise immunity and reliable operation with slow or noisy input transitions. Each gate follows the standard NOR truth table (L/L → H, L/H → L, H/L → L, H/H → L) and supports bidirectional voltage translation across 1.65 V–5.5 V domains.

The IOFF circuit actively disables outputs when V_CC = 0 V, blocking backflow current during partial power-down-critical for hot-swap and power-gated subsystems. Input overvoltage tolerance up to 5.5 V and 5 V-tolerant outputs allow direct interfacing with legacy TTL and 5 V CMOS logic without external level shifters.

FAQ

Does 74LVC2G02DP-Q100 support true bidirectional level shifting?

No - it is a unidirectional logic gate with 5 V-tolerant inputs and outputs, not a dedicated level shifter. Signal flow is strictly input→output; it cannot pass data from output to input. For bidirectional translation (e.g., I²C), a purpose-built device like the NXH0102UK is required.

What is the maximum capacitive load this device can drive reliably?

At V_CC = 3.3 V and Tamb = 85 °C, the device maintains <6 ns propagation delay driving ≤30 pF (per output), as verified in the datasheet test setup. Driving >50 pF may increase delay unpredictably and reduce noise margin; add series termination for loads exceeding 30 pF.

Can IOFF functionality be used during dynamic operation?

No - IOFF activates only when V_CC = 0 V. It does not respond to logic-level control signals. To achieve active output disable, use an external enable signal routed through a third gate or select a variant with OE pin (e.g., 74LVC2G125).

Is the Schmitt-trigger hysteresis specified over temperature?

Yes - hysteresis is guaranteed ≥0.3 V across −40 °C to +125 °C, derived from VIH/VIL specifications: ΔV = VIH_min − VIL_max = (0.65×V_CC) − (0.35×V_CC) = 0.3×V_CC, and minimum V_CC = 1.65 V yields ≥0.495 V hysteresis at worst case.
