Product details
Overview
NLV74HC03ADTR2G from onsemi is a quad 2-input NAND gate with open-drain outputs, implemented in high-performance silicon-gate CMOS technology. It operates across 2.0–6.0 V supply, delivers sinking current up to 25 mA per output, supports wired-AND logic and LED driving, and is pinout-compatible with LS03 for legacy TTL system upgrades.
For engineers reviewing the NLV74HC03ADTR2G datasheet, pinout, applications, or equivalent options, this device is selected for level-shifting interfaces, active-low bus arbitration, LED sink control, and mixed-voltage logic interfacing where open-drain flexibility and rail-to-rail input compatibility are required.
Technical Context
The NLV74HC03ADTR2G integrates four independent NAND gates, each featuring an N-channel MOSFET output stage without internal pull-up-requiring external pull-up resistors for logic-high assertion. Its inputs accept both CMOS and LSTTL voltage levels when pulled up, enabling direct interface with legacy TTL and modern low-voltage logic families.
Propagation delay ranges from 20 ns (at VCC = 6.0 V) to 180 ns (at VCC = 2.0 V, TA ≤ 125°C), and output transition time is as fast as 13 ns under same conditions. The device exhibits low input leakage (±1.0 µA max at 6.0 V) and high noise immunity inherent to CMOS architecture, supporting robust operation in industrial and automotive environments.

FAQ
What is the maximum sink current per output of the NLV74HC03ADTR2G?
The NLV74HC03ADTR2G specifies a maximum DC output sink current of ±25 mA per pin, verified across −55 °C to +125 °C. This rating allows direct LED driving or interfacing with multiple LSTTL loads when used with an appropriate external pull-up resistor. Exceeding this value risks parametric shift or long-term reliability degradation.
Does the NLV74HC03ADTR2G support wired-AND functionality?
Yes, the NLV74HC03ADTR2G supports wired-AND by design: its four open-drain outputs can be tied together with a shared pull-up resistor to implement active-low bus arbitration or logic combining. Figure 6 in the official datasheet explicitly illustrates this configuration, confirming that Y1•Y2•...•Yn = A1B1•A2B2•...•AnBn in such topologies.
Is the NLV74HC03ADTR2G pin-compatible with the 74LS03?
Yes, the NLV74HC03ADTR2G is pinout-identical to the 74LS03, as confirmed in the datasheet's first paragraph: "The MC74HC03A is identical in pinout to the LS03." This enables direct replacement in legacy TTL designs without PCB modification, provided supply voltage and timing margins are validated.
What is the operating temperature range of the NLV74HC03ADTR2G?
The NLV74HC03ADTR2G is rated for −55 °C to +125 °C operating free-air temperature, meeting AEC-Q100 Grade 1 requirements. This extended range distinguishes it from commercial variants like MC74HC03ADTR2G (−40 °C to +85 °C) and supports deployment in under-hood automotive modules and outdoor industrial enclosures.
Can the NLV74HC03ADTR2G be used as an LED driver?
Yes, the NLV74HC03ADTR2G is explicitly validated as an LED driver in Figure 7 of the datasheet, which provides a design example with 10 mA sink current, 0.4 V saturation voltage, and 270 Ω pull-up resistor at 5 V. Its open-drain outputs allow flexible current-setting via external resistor selection and support PWM dimming when driven by microcontroller GPIOs.
