Nexperia USA Inc. 74LVC02ADB,118

Overview

74LVC02ADB,118 from Nexperia is a quad 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, 1.2 V to 3.6 V supply operation, and -40 °C to +125 °C temperature range. It delivers propagation delay as low as 2.2 ns at 3.0–3.6 V and supports 24 mA output drive capability.

For engineers reviewing the 74LVC02ADB,118 datasheet, 74LVC02ADB,118 pinout, 74LVC02ADB,118 application, or 74LVC02ADB,118 equivalent, this device is selected for mixed-voltage digital interfacing, bus arbitration, and reset signal conditioning in industrial control, embedded peripherals, and FPGA I/O bridging where input hysteresis and rail-to-rail compatibility are critical.

Technical Context

This device implements four independent 2-input NOR gates with CMOS architecture, enabling rail-to-rail logic-level translation across 1.2–3.6 V supplies while tolerating up to 5.5 V on inputs. Its Schmitt-trigger inputs provide ≥0.3 V hysteresis, improving noise margin against slow-rising signals in noisy environments.

Each gate exhibits matched propagation delays (tpd ≤ 5.5 ns max at VCC = 3.0–3.6 V) and low output skew (tsk(o) ≤ 1.5 ns), ensuring timing coherence across all four channels. Input leakage remains ≤ ±20 μA at 3.6 V supply and 5.5 V input, supporting reliable high-impedance interface monitoring.

FAQ

What is the maximum input voltage the 74LVC02ADB,118 can tolerate?

The 74LVC02ADB,118 accepts input voltages up to 5.5 V regardless of VCC setting - a key feature enabling direct interfacing with 5 V TTL outputs in mixed-voltage systems. This overvoltage tolerance is guaranteed per JEDEC JESD78 and does not require external clamping diodes or resistors.

Does the 74LVC02ADB,118 require external pull-up or pull-down resistors on unused inputs?

No - all inputs feature integrated Schmitt-trigger circuitry with defined thresholds and hysteresis, eliminating floating input states. Unused inputs should be tied HIGH or LOW directly to VCC or GND; no external resistors are needed for stability or noise immunity.

Can the 74LVC02ADB,118 operate at 1.2 V supply while driving a 30 pF load?

Yes - the device is fully specified down to 1.2 V supply, with propagation delay of 14 ns (typical) and output drive capability maintained. At 1.2 V, VOL remains ≤0.12 V at 100 μA sink current, ensuring valid LOW-level signaling into standard LVC inputs with 30 pF loading.

Is the SOT337-1 (SSOP14) package of 74LVC02ADB,118 RoHS compliant and lead-free?

Yes - the 74LVC02ADB,118 uses a lead-free, halogen-free, RoHS-compliant SOT337-1 package per Nexperia's product compliance documentation. The device meets EU RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level MSL3.
