Nexperia USA Inc. 74LV03D,112

Overview

74LV03D,112 from Nexperia is a quad 2-input NAND gate IC with open-drain outputs, designed for level-shifting and wired-AND bus interfacing in mixed-voltage systems. It operates across 1.0 V to 5.5 V supply, delivers propagation delay as low as 8 ns at 3.3 V/15 pF, supports -40 °C to +125 °C ambient range, and features input clamp diodes enabling safe interface to voltages exceeding VCC - used in I²C bus pull-up networks and voltage-level translation between 3.3 V and 5 V domains.

For engineers reviewing the 74LV03D,112 datasheet, 74LV03D,112 pinout, 74LV03D,112 application, or 74LV03D,112 equivalent, key selection criteria include open-drain output drive capability (12 mA sink at 4.5 V), wide VCC tolerance (1.0–5.5 V), input clamping for overvoltage resilience, and SO14 package compatibility with legacy 74-series footprints.

Technical Context

The 74LV03D,112 implements four independent 2-input NAND gates, each with open-drain output topology requiring external pull-up resistors. Its CMOS input structure includes integrated clamp diodes to GND and VCC, allowing direct connection to signals up to 6.0 V when VCC ≥ 1.0 V - critical for mixed-supply logic interfacing.

Propagation delay varies with supply voltage: 50 ns at 1.2 V, 13 ns at 5.5 V, and 8 ns typical at 3.3 V with 15 pF load. Static characteristics are guaranteed from -40 °C to +125 °C, and latch-up immunity exceeds 100 mA per JESD78 Class II Level B.

FAQ

Can 74LV03D,112 drive a 5 V pull-up resistor while powered from 3.3 V?

Yes - its open-drain outputs can sink current from any voltage up to 6.0 V, and its input clamp diodes allow safe connection to 5 V signals when VCC = 3.3 V, provided series current-limiting resistors limit input clamp current to ≤20 mA per pin.

Is 74LV03D,112 pin-compatible with standard 74HC03 or 74LS03?

No - while the SO14 pinout matches the industry-standard 14-pin logic layout (GND at pin 7, VCC at pin 14), the 74LV03D,112 has open-drain outputs versus push-pull in 74HC03/74LS03, requiring external pull-ups and preventing direct functional substitution without circuit redesign.

What is the maximum capacitive load the 74LV03D,112 can drive reliably?

The datasheet specifies dynamic performance up to 50 pF load capacitance with defined rise/fall times and propagation delay. For reliable operation beyond 50 pF, derate VCC or add a buffer stage - CPD = 4 pF indicates low dynamic power consumption even at high frequencies.

Does 74LV03D,112 support partial power-down or I/O isolation when VCC = 0 V?

No - the device lacks Ioff (power-off protection) specification. When VCC = 0 V, inputs and outputs may conduct if external voltages are applied, risking back-powering or latch-up. Use Ioff-enabled alternatives like 74LVC03 if hot-insertion or partial power-down is required.
