Product details

Overview

74VHC03MTR from STMicroelectronics is a quad 2-input open-drain NAND gate in SO-14 package, operating from 2V to 5.5V supply, with 3.7ns typical propagation delay at 5V, 2µA max quiescent current at 25°C, and input tolerance up to 7V independent of VCC-used for wired-AND bus interfacing and LED current-sinking drivers.

For engineers reviewing the 74VHC03MTR datasheet, 74VHC03MTR pinout, 74VHC03MTR application, or 74VHC03MTR equivalent, key selection criteria include open-drain output drive capability (8mA sink at 4.5V), input overvoltage tolerance (0–7V), latch-up immunity, ESD protection (2kV HBM), and 5V-to-3V level-shifting compatibility.

Technical Context

The 74VHC03MTR implements four independent NAND gates with open-drain outputs, requiring external pull-up resistors for logic high assertion. Its sub-micron C2MOS process enables high noise immunity (VIH/VIL = 0.7VCC/0.3VCC) and stable output buffering across temperature (−55°C to +125°C).

All inputs feature power-down protection and accept 0–7V regardless of VCC state, enabling hot-swap and mixed-voltage interface operation. Output leakage is ≤±2.5µA at 5.5V, and dynamic noise parameters (VOLP ≤ 0.8V, VOLV ≥ −0.8V) are specified under 50pF load at 5V.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2V to 5.5V - supports dual-supply systems and 3.3V/5V mixed-rail interfacing
t_PD (Typ.)	3.7ns at V_CC = 5V - enables high-speed bus arbitration and timing-critical control paths
I_CC (Max)	2µA at T_A = 25°C - ultra-low static power for battery-backed or always-on logic
I_O Sink	8mA at V_CC = 4.5V - sufficient for direct LED driving or I²C-bus pull-down
V_IN Range	0V to 7V independent of V_CC - allows safe interfacing with higher-voltage peripherals
ESD Rating	2kV HBM - protects against handling-induced discharge without external clamping
V_NIH/V_NIL	28% V_CC (min) - ensures robust noise margin in electrically noisy industrial environments

Pinout & Package

74VHC03MTR is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package with standard 1.27mm pitch, tape-and-reel packaging (MTR suffix), and JEDEC-compliant mechanical dimensions (8.55–8.75mm length, 3.8–4.0mm width).

Pin/Terminal	Circuit Role	Design Meaning
1, 4, 9, 12	Input A (Gate 1–4)	Active-high data input per NAND gate; tolerant to 0–7V regardless of V_CC
2, 5, 10, 13	Input B (Gate 1–4)	Second active-high input per gate; shares same overvoltage and power-down protection
3, 6, 8, 11	Output Y (Gate 1–4)	Open-drain output - requires external pull-up; sinks up to 8mA at 4.5V
7	GND	Ground reference for all internal circuitry and I/O; decoupling capacitor connection point
14	V_CC	Positive supply rail (2–5.5V); powers internal logic but does not limit input voltage range

Key Features

Feature	Design Value
Open-drain outputs	Enable wired-AND bus topology and bidirectional I²C/SMBus communication without contention
Input overvoltage tolerance	0–7V input range independent of V_CC allows safe interfacing with 5V peripherals on 3.3V systems
Power-down input protection	Inputs remain functional and non-latching even when V_CC = 0V - critical for hot-plug applications
High noise immunity	28% V_CC noise margin ensures reliable operation in motor-drive or switching-power-supply proximity
Low dynamic noise	VOLP ≤ 0.8V and VOLV ≥ −0.8V minimize crosstalk in dense PCB layouts with 50pF loads

Applications

Use Scenario: Translating signals between 3.3V microcontroller GPIOs and 5V I²C peripherals.

IC Role / Device Role / Timing Role: Open-drain NAND configured as bidirectional level translator with pull-ups on both sides.

Use Scenario: Driving common-anode LED rows in multiplexed 8×8 displays.

IC Role / Device Role / Timing Role: Current-sinking driver for row select lines; synchronized with column drivers via microcontroller.

Use Value: Delivers 8mA sink per output at 4.5V - sufficient for bright LEDs without external transistors.

Wired-AND Interrupt Bus

Mixed-Voltage System Interface

Use Scenario: Aggregating interrupt requests from multiple 5V sensors into a single 3.3V MCU interrupt line.

IC Role / Device Role / Timing Role: Wired-AND combiner using open-drain outputs tied to shared pull-up resistor.

Use Value: Input accepts 0–7V, output swings rail-to-rail - enables direct connection without resistive dividers.

Equivalent & Alternatives

The following parts are listed as comparable options for similar open-drain NAND gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC03APWR	3.3V-only V_CC range (1.65–3.6V); lower t_PD (3.1ns typ.); no 7V input tolerance	Not suitable for 5V system interfacing or hot-swap scenarios	Prefer when operating exclusively in 3.3V domains with tighter timing budgets
74AHC03PW,118	Wider V_CC (2–5.5V) and 7V input tolerance retained; higher I_O sink (12mA at 4.5V); slightly higher ICC (4µA)	Better for high-current LED loads; identical pinout and logic function	Select when >8mA sink capability is required without changing layout or firmware

Compared with SN74LVC03APWR and 74AHC03PW,118, the 74VHC03MTR offers superior input overvoltage safety and lowest quiescent current, making it optimal for mixed-voltage industrial interfaces where reliability and power efficiency are prioritized over peak speed or maximum drive strength.

FAQ

Can 74VHC03MTR be used without an external pull-up resistor?

No. Its open-drain outputs require external pull-up resistors to assert logic HIGH. Without pull-ups, outputs remain floating or weakly pulled low via leakage. Typical values range from 1kΩ (for speed-critical I²C) to 10kΩ (for low-power LED indicators), selected based on load capacitance and rise-time requirements.

Does 74VHC03MTR support hot-swap insertion when V_CC is unpowered?

Yes. Power-down protection on all inputs allows 0–7V signals to be applied even when V_CC = 0V, preventing latch-up or damage during live insertion. This is confirmed by absolute maximum ratings and input equivalent circuit diagrams in the official ST datasheet Rev. 4.

What is the maximum capacitive load the 74VHC03MTR can drive reliably?

The device is characterized up to 50pF load (per AC specs), with t_PZL/t_PLZ tested at CL = 15pF and 50pF. Driving >50pF may increase propagation delay and degrade VOLP/VOLV noise margins; for heavier loads, add a series resistor or buffer stage to maintain signal integrity.

Is 74VHC03MTR pin-compatible with standard 74LS03 or 74HC03?

It is functionally and pin-compatible with 74HC03 (same pinout, truth table, and open-drain behavior) but not with 74LS03, which uses bipolar technology, has different voltage thresholds, and lacks 7V input tolerance. The "VHC" prefix denotes advanced CMOS with enhanced speed and noise immunity over HC.
