Nexperia USA Inc. 74LVC1G02GZYL

Overview

74LVC1G02GZYL from Nexperia is a single 2-input NOR gate logic IC designed for level translation between 3.3 V and 5 V systems, featuring Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and ±24 mA output drive at 3.0 V. It operates across 1.65 V to 5.5 V supply and supports industrial temperature range (–40 °C to +125 °C) in XSON5 package with side-wettable flanks.

For engineers reviewing the 74LVC1G02GZYL datasheet, 74LVC1G02GZYL pinout, 74LVC1G02GZYL application, or 74LVC1G02GZYL equivalent, key selection criteria include mixed-voltage interface capability, IOFF-enabled system power sequencing, Schmitt-trigger input tolerance for slow edges, and thermal-enhanced XSON5 packaging for high-density PCB layouts.

Technical Context

This device implements standard positive-logic NOR functionality (Y = NOT(A OR B)) with rail-to-rail CMOS output swing and input thresholds compliant with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36 across its full 1.65 V–5.5 V supply range. Input overvoltage tolerance up to 5.5 V enables safe interfacing with higher-voltage signal sources without external clamping.

The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during partial power-down - critical for hot-swap and multi-rail system designs. Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at 3.3 V), enabling reliable operation with slow-rising/falling signals (Δt/ΔV ≤ 10 ns/V above 2.7 V).

FAQ

Can 74LVC1G02GZYL operate with VCC = 1.65 V while accepting 3.3 V inputs?

Yes. Its inputs are overvoltage tolerant up to 5.5 V regardless of VCC level, so 3.3 V signals may be safely applied even when powered at minimum 1.65 V. This enables true bidirectional level translation without external components or direction control.

What is the maximum capacitive load this device can drive at 10 MHz?

At VCC = 3.3 V and 10 MHz toggle rate, dynamic power dissipation remains within limits for ≤50 pF total load (including PCB trace and receiver input capacitance), based on CPD = 14 pF and PD = CPD × VCC² × fi × N. Exceeding this requires verifying VOL/VOH margins under actual load conditions.

Does the IOFF feature protect against back-current when only GND is disconnected?

No. IOFF activation requires VCC = 0 V; if only GND is open while VCC remains active, the device lacks a return path and may latch-up or suffer damage. IOFF safeguards only against backfeed during controlled VCC ramp-down, not floating ground scenarios.

How does the Schmitt-trigger input improve reliability in noisy factory environments?

With typical hysteresis of 0.3 V at 3.3 V, the input threshold shifts between ~1.35 V (rising) and ~1.05 V (falling), rejecting noise spikes <0.3 V peak-to-peak and preventing false toggling on long cables or near motor drives - eliminating need for external RC filtering.
