Nexperia USA Inc. 74LVC00ABQ,115

Overview

74LVC00ABQ,115 from Nexperia is a quad 2-input NAND gate in DHVQFN14 (SOT762-1) 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, supports mixed 3.3 V/5 V logic translation, and is rated for -40 °C to +125 °C operation. Used in level-shifting, signal conditioning, and digital control logic in industrial I/O modules.

For engineers reviewing the 74LVC00ABQ,115 datasheet, 74LVC00ABQ,115 pinout, 74LVC00ABQ,115 application, or 74LVC00ABQ,115 equivalent, key selection criteria include input voltage tolerance (5.5 V), propagation delay (≤5.1 ns at 3.3 V), thermal-enhanced QFN package, rail-to-rail output swing, and JEDEC-compliant ESD robustness (HBM >2000 V).

Technical Context

This device implements four independent CMOS NAND gates with Schmitt-trigger inputs-enabling reliable operation with slow-rising or noisy signals. Each gate exhibits identical logic behavior: output HIGH when either input is LOW, output LOW only when both inputs are HIGH.

Its wide 1.2 V–3.6 V VCC range and 5.5 V input tolerance allow direct interfacing between legacy 5 V TTL and modern low-voltage 1.8 V/2.5 V/3.3 V systems without external level shifters. The DHVQFN14 package provides enhanced thermal performance versus SO14 or TSSOP variants.

FAQ

Can 74LVC00ABQ,115 operate with a 1.2 V supply and still interface with 5 V inputs?

Yes. The device is fully specified down to 1.2 V VCC and supports input voltages up to 5.5 V independent of supply level. This allows direct connection of 5 V signals-such as from legacy microcontrollers or sensors-to the inputs without damage or level-shifting circuitry, while outputs swing rail-to-rail relative to the 1.2 V supply.

What is the maximum output current per pin, and how does it vary with supply voltage?

The absolute maximum output current is ±24 mA per output pin at VCC = 3.0 V. At lower supplies, drive capability scales approximately linearly: ±12 mA at 1.8 V and ±8 mA at 1.2 V. These values are validated across the full -40 °C to +125 °C temperature range and define the guaranteed sink/source capability before VOL/VOH limits are exceeded.

Is the exposed thermal pad on the DHVQFN14 package required to be soldered to ground?

No. Per Nexperia's datasheet (Section 5.1), the thermal pad is not electrically connected and has no mandatory solder requirement. If soldered, it must remain floating or be tied to GND-never to VCC or any other potential. Its primary role is thermal conduction, not electrical functionality.

How does the Schmitt-trigger input improve noise immunity compared to standard CMOS inputs?

Schmitt-trigger inputs provide hysteresis-typically ~0.3 V at 3.3 V VCC-meaning the rising threshold (VIH) is significantly higher than the falling threshold (VIL). This prevents multiple output toggles when input signals cross the logic threshold slowly or with noise, making the device ideal for debouncing switches, recovering clock edges from noisy sensors, or interfacing with slow RC time-constant signals.
