NXP Semiconductors 74LVT02D,118

Overview

74LVT02D,118 from Nexperia is a 3.3 V quad 2-input NOR gate in SO14 package, featuring IOFF partial power-down protection, ±64 mA/–32 mA output drive, 5.5 V overvoltage-tolerant inputs, and operation from –40 °C to +85 °C. It serves as a level-shifting logic buffer in mixed-voltage digital control planes, such as FPGA I/O expansion and industrial PLC backplane interfaces.

For engineers reviewing the 74LVT02D,118 datasheet, 74LVT02D,118 pinout, 74LVT02D,118 application, or 74LVT02D,118 equivalent, this device is selected for robust bus interfacing where 3.3 V logic must coexist with 5 V legacy systems while maintaining latch-up immunity and zero bus loading during power-down.

Technical Context

The 74LVT02D,118 implements four independent NOR gates with TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and rail-to-rail output swing under 3.3 V supply. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking reverse current flow into powered-down sections of the system.

Propagation delays are specified at 2.6–4.4 ns (tPHL/tPLH) across 2.7–3.6 V supply and –40 °C to +85 °C ambient. Input clamping voltage is –1.2 V (VIK), and static input leakage remains ≤ ±1 μA at VCC = 3.6 V - enabling reliable operation in noisy industrial environments.

FAQ

Does 74LVT02D,118 support hot-swap insertion into a live 5 V bus?

Yes - its 5.5 V overvoltage-tolerant inputs and IOFF circuitry allow safe insertion while VCC is unpowered. When VCC = 0 V, outputs go high-impedance and input leakage remains ≤ ±100 μA, preventing bus disruption or damage to upstream drivers.

Can 74LVT02D,118 drive a 50 pF load at 10 MHz without signal degradation?

Yes - with tPLH/tPHL ≤ 4.4 ns at 3.3 V and +64 mA sink capability, it maintains clean edges into 50 pF loads at 10 MHz. The datasheet confirms stable operation up to 50 pF with RL = 500 Ω and CL = 50 pF in the dynamic test setup.

What is the maximum junction temperature during continuous operation at 85 °C ambient?

At Tamb = +85 °C, Ptot = 500 mW (SO14), and thermal resistance θJA ≈ 90 °C/W, Tj reaches ~162 °C - exceeding the 150 °C absolute max. Derating is required: maximum allowable power at 85 °C ambient is ~380 mW to hold Tj ≤ 150 °C.

Is there a pin-compatible TSSOP alternative to 74LVT02D,118?

Yes - 74LVT02PW in SOT402-1 (TSSOP14) shares identical logic function, pinout, and electrical specs. It offers smaller footprint (4.4 mm width) and lower profile but has different thermal derating: Ptot linearly decreases by 7.3 mW/K above 81 °C.
