Nexperia USA Inc. 74LVC2G02DC-Q100H

Overview

74LVC2G02DC-Q100 from Nexperia is a dual 2-input NOR gate logic IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 1.65 V to 5.5 V, 5 V-tolerant inputs/outputs, and ±24 mA output drive at V_CC = 3.0 V. It enables level translation between 3.3 V and 5 V domains in body control modules and infotainment interfaces.

For engineers reviewing the 74LVC2G02DC-Q100 datasheet, 74LVC2G02DC-Q100 pinout, 74LVC2G02DC-Q100 application, or 74LVC2G02DC-Q100 equivalent, key selection criteria include IOFF-enabled partial power-down capability, Schmitt-trigger input hysteresis for noise immunity, propagation delay down to 0.6 ns at 5 V, and VSSOP8 package compatibility with high-density PCB layouts.

Technical Context

This device implements two independent 2-input NOR gates in a single monolithic CMOS structure, each with Schmitt-trigger inputs enabling robust operation with slow-rising signals and high noise immunity. The IOFF circuit actively disables outputs during power-down, preventing backflow current when V_CC = 0 V.

It supports mixed-voltage interfacing via 5.5 V overvoltage-tolerant inputs and 5 V-tolerant outputs, compliant with JEDEC standards JESD8-7, JESD8-5, and JESD8-B/JESD36 across its full 1.65–5.5 V supply range. Propagation delay varies from 0.6 ns (V_CC = 4.5–5.5 V) to 11.2 ns (V_CC = 1.65–1.95 V, T_amb = –40 to +125 °C).

FAQ

What is the maximum allowable input voltage when V_CC = 0 V?

The 74LVC2G02DC-Q100 supports overvoltage-tolerant inputs up to 5.5 V regardless of V_CC state. When V_CC = 0 V, the IOFF circuit isolates outputs, but inputs remain rated to 5.5 V per Table 5 - enabling safe hot-plug operation in modular automotive architectures where supply rails may be sequenced independently.

Does this device support true bidirectional level shifting?

No. The 74LVC2G02DC-Q100 is a unidirectional logic gate: inputs accept 1.65–5.5 V signals and outputs drive 0–V_CC levels. While its 5 V-tolerant inputs allow interfacing with 5 V sources when powered at 3.3 V, it lacks internal circuitry for automatic direction detection or data flow reversal required for true bidirectional translation.

How does the Schmitt-trigger input affect timing analysis?

Schmitt-trigger inputs introduce hysteresis (~0.3 V typical), meaning the threshold for rising-edge detection (V_IH) differs from falling-edge detection (V_IL). This eliminates metastability from slow edges but requires using worst-case propagation delays from Table 8 - e.g., 11.2 ns at 1.65 V over –40 to +125 °C - rather than typical values, especially in switch debounce or analog comparator output conditioning.

Can this NOR gate be used to implement an oscillator?

Yes, by connecting output to input through an RC network - but not recommended for precision timing. The device's propagation delay (0.6–11.2 ns) and input hysteresis create relaxation oscillation, yet frequency stability is highly sensitive to V_CC, temperature, and load capacitance. Automotive designs requiring timing should use dedicated oscillators or crystal-based solutions instead.
