Nexperia USA Inc. 74LVC1G02GV-Q100H

Overview

74LVC1G02GV-Q100 from Nexperia is a single 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, ±24 mA output drive at V_CC = 3.0 V, and IOFF-enabled partial power-down protection. It serves as a level-translating combinational logic element in mixed-voltage signal routing, such as wake-up detection or fault-condition arbitration in body control modules.

For engineers reviewing the 74LVC1G02GV-Q100 datasheet, 74LVC1G02GV-Q100 pinout, 74LVC1G02GV-Q100 application, or 74LVC1G02GV-Q100 equivalent, key selection criteria include its overvoltage-tolerant 5.5 V inputs, Schmitt-trigger input hysteresis for noise immunity, IOFF leakage < ±2 μA during power-down, and guaranteed propagation delay ≤ 6.0 ns at V_CC = 3.3 V.

Technical Context

This device implements standard positive-logic NOR functionality (Y = NOT(A OR B)) with Schmitt-trigger inputs enabling robust operation under slow-rising or noisy signals. Its IOFF circuit actively disables outputs when V_CC = 0 V, preventing backflow current in hot-swap or partial-power-down systems.

It supports bidirectional voltage translation between 3.3 V and 5 V domains due to 5.5 V-tolerant inputs and CMOS-compatible output levels. Static and dynamic performance is specified across full automotive temperature range (-40 °C to +125 °C), with VIH/VIL thresholds scaling with V_CC per JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36.

FAQ

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

The 74LVC1G02GV-Q100 permits input voltages up to 5.5 V even when unpowered (V_CC = 0 V), thanks to integrated input clamping diodes and overvoltage-tolerant design. This enables safe hot-plug operation and eliminates need for external protection in mixed-rail systems.

Does this device support true bidirectional level translation?

No - it supports unidirectional level translation only: inputs accept 0–5.5 V signals while outputs swing rail-to-rail between GND and V_CC. For bidirectional translation (e.g., I²C), a dedicated bus switch or pass-gate device is required.

How does the IOFF feature behave during power sequencing?

When V_CC drops below ~0.2 V, the IOFF circuit forces Y into high-impedance state within nanoseconds, blocking current flow from powered downstream circuits back into the unpowered gate - critical for preventing latch-up in multi-supply domains.

Can this NOR gate drive a 50 pF load at 10 MHz without signal degradation?

Yes - with CPD = 14 pF and t_pd ≤ 6.0 ns at V_CC = 3.3 V, the device delivers clean edges into 50 pF loads at 10 MHz. Dynamic power dissipation remains under 1.5 mW (PD = CPD × V_CC² × f_i × N), well within its 250 mW P_tot limit at +85 °C.
