Nexperia USA Inc. 74LVC00AD,118

Overview

74LVC00AD,118 from Nexperia is a quad 2-input NAND gate in SO14 (SOT108-1) package, operating from 1.2 V to 3.6 V supply with overvoltage-tolerant inputs up to 5.5 V. It features Schmitt-trigger inputs for noise immunity and supports mixed-voltage translation between 3.3 V and 5 V logic domains. Used in digital control logic, bus interfacing, and level-shifting circuits in industrial controllers and embedded peripherals.

For engineers reviewing the 74LVC00AD,118 datasheet, 74LVC00AD,118 pinout, 74LVC00AD,118 application, or 74LVC00AD,118 equivalent, key selection criteria include input voltage tolerance (5.5 V), propagation delay (≤5.1 ns at 3.3 V), wide temperature range (−40 °C to +125 °C), and SO14 package compatibility with legacy PCB footprints.

Technical Context

The 74LVC00AD,118 implements four independent NAND gates with CMOS architecture and Schmitt-trigger inputs-enabling robust operation with slow-rising/falling signals and reducing susceptibility to noise-induced glitches. Each gate exhibits identical logic behavior defined by H/L/X truth table with no internal feedback or state retention.

It operates across three JEDEC-compliant voltage ranges (1.65–1.95 V, 2.3–2.7 V, 2.7–3.6 V) and supports direct TTL-level interfacing while maintaining low ICC (≤40 μA at 3.6 V). Input clamping current rating of ±50 mA and HBM ESD protection >2000 V ensure resilience in noisy industrial environments.

FAQ

Can 74LVC00AD,118 be used with a 5 V microcontroller output driving its inputs?

Yes. Its inputs are overvoltage tolerant up to 5.5 V regardless of VCC setting (1.2–3.6 V), enabling direct connection to 5 V GPIOs without level-shifting components. Internal clamping diodes limit input current to ±50 mA, and HBM ESD rating exceeds 2000 V-ensuring robustness in real-world industrial environments.

What is the maximum capacitive load this device can drive while maintaining specified propagation delay?

At VCC = 3.3 V and Tamb = 25 °C, the 74LVC00AD,118 maintains tpd ≤5.1 ns into a 50 pF load with 500 Ω termination, per test conditions in Table 8. Driving >50 pF increases delay nonlinearly and may cause ringing; for >100 pF loads, add series termination or buffer staging per application note AN10754.

Does the SO14 package (SOT108-1) have thermal performance limitations at +125 °C ambient?

Yes. The SO14 package has RθJA ≈ 110 K/W. At +125 °C ambient and full 24 mA output loading per gate, junction temperature may exceed 150 °C. Derate total power dissipation linearly above 100 °C at 10.1 mW/K. For sustained high-load operation above 100 °C, consider DHVQFN14 (74LVC00ABQ) with RθJA ≈ 60 K/W.

How does Schmitt-trigger input behavior affect timing in slow-edge applications?

Schmitt-trigger inputs provide ~0.3 V hysteresis at VCC = 3.3 V, ensuring clean, bounce-free transitions even with rise/fall times up to 20 ns/V (i.e., 200 ns for 10 V edge). This eliminates need for external RC filtering in switch debouncing or sensor signal conditioning-reducing BOM count and PCB area while guaranteeing deterministic gate switching.
