Nexperia USA Inc. 74HCT03PW-Q100J

Overview

74HCT03PW-Q100 from Nexperia is an automotive-qualified quad 2-input NAND gate with open-drain outputs, designed for level-shifting and wired-AND bus interfacing in vehicle control modules. It operates from 4.5 V to 5.5 V, delivers TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max), supports -40 °C to +125 °C ambient, and features clamp diodes enabling overvoltage-tolerant input interfacing.

For engineers reviewing the 74HCT03PW-Q100 datasheet, 74HCT03PW-Q100 pinout, 74HCT03PW-Q100 application, or 74HCT03PW-Q100 equivalent, this device is selected for robust digital logic interfacing in automotive powertrain ECUs, body control units, and infotainment system I²C pull-up networks where open-drain drive and AEC-Q100 Grade 1 compliance are mandatory.

Technical Context

This device implements four independent NAND gates, each with open-drain output topology requiring external pull-up resistors. Its TTL-level input compatibility ensures direct connection to legacy microcontroller GPIOs without level translation. The internal clamp diodes on all inputs allow safe operation when interfacing to signals exceeding VCC - a key requirement for mixed-voltage domain communication in modern automotive electronics.

Propagation delay is specified at 12 ns (typ) to 36 ns (max) across temperature and voltage, with transition times under 22 ns (max), supporting reliable operation up to ~20 MHz in wired-AND configurations. The device exhibits low static current (ICC ≤ 40 μA at 125 °C) and high noise immunity due to hysteresis-free CMOS design with VIH/VIL margins exceeding 1.2 V at VCC = 5.0 V.

FAQ

What is the maximum sink current per open-drain output?

Each open-drain output is rated for a continuous sink current of 5.2 mA at VCC = 4.5 V and VO = 0.4 V, verified across -40 °C to +125 °C. This value is derived from the VOL specification (≤ 0.4 V at IO = 5.2 mA) in Table 6 of the official Nexperia datasheet Rev. 4. Exceeding this current risks violating output voltage limits and degrading noise margins.

Can 74HCT03PW-Q100 be used with a 3.3 V supply?

No - the 74HCT03PW-Q100 is specified only for 4.5 V to 5.5 V operation per Table 5. Its TTL-compatible inputs require VIH ≥ 2.0 V, but the internal logic threshold scaling depends on VCC; operation below 4.5 V violates recommended conditions and may cause unreliable switching or increased ICC. For 3.3 V systems, use 74LVC03 or 74AHC03 variants instead.

How does the input clamp diode affect external resistor selection?

The integrated clamp diodes allow input voltages up to VCC + 0.5 V without damage, enabling use of current-limiting resistors when interfacing to higher-voltage sources (e.g., 12 V sensors). To limit IIK to ≤ ±20 mA (absolute max), select R ≥ |VIN − VCC| / 20 mA - e.g., for 12 V input and 5 V VCC, R ≥ 350 Ω. This eliminates need for external Schottky clamps.

Is the 74HCT03PW-Q100 pin-compatible with standard 74HCT03 devices?

Yes - the pinout matches JEDEC-standard TSSOP-14 (SOT402-1) layout: inputs and outputs follow identical numbering (1A=pin1, 1B=pin2, 1Y=pin3, ..., VCC=pin14, GND=pin7). No footprint or routing changes are needed when upgrading from commercial-grade 74HCT03PW to this AEC-Q100 qualified version, provided thermal and qualification requirements are met.
