STMicroelectronics 74V2G02STR

Overview

74V2G02STR from STMicroelectronics is a dual 2-input NOR gate IC in SOT23-8L package, operating from 2V to 5.5V, with 3.6ns typical propagation delay at 5V, ±8mA symmetrical output drive, and input tolerance up to 7V independent of VCC-enabling robust 5V-to-3V level translation in mixed-voltage logic interfaces.

For engineers reviewing the 74V2G02STR datasheet, 74V2G02STR pinout, 74V2G02STR application, or 74V2G02STR equivalent, key selection criteria include its dual-gate logic function, rail-to-rail input voltage support (0–7V), sub-10ns AC timing across 3.3V/5V operation, latch-up immunity, and power-down protected inputs for hot-swap compatibility.

Technical Context

This device implements two independent CMOS NOR gates using sub-micron C2MOS technology with three-stage buffered outputs, delivering balanced tPLH/tPHL delays and high noise immunity (VNIH/VNIL ≥28% VCC). Its input structure accepts voltages from –0.5V to 7.0V regardless of VCC, enabling safe interfacing between disparate supply domains.

The internal design includes diode-clamped inputs with power-down protection, symmetrical ±8mA output drive capability at 4.5V, and quiescent ICC ≤1µA at 25°C-making it suitable for low-power, mixed-supply digital signal routing where voltage translation and transient resilience are critical.

FAQ

Can the 74V2G02STR safely interface a 5V sensor output to a 3.3V microcontroller input?

Yes. Its inputs tolerate 0–7V regardless of VCC, and with VCC = 3.3V, it produces valid CMOS output levels compatible with 3.3V logic families. No external resistors or level shifters are required, and power-down protection prevents backfeeding when the MCU is unpowered.

What is the maximum capacitive load this device can drive while maintaining specified propagation delay?

The AC specifications guarantee tPD ≤7.5ns (max) at VCC = 5.0V with CL = 50pF. Driving loads beyond 50pF increases delay nonlinearly and may degrade edge rate; for >50pF, derating curves in the datasheet show tPD ≈9.5ns at 100pF, so layout capacitance must be minimized in high-speed paths.

Does the 74V2G02STR require external pull-up or pull-down resistors on unused inputs?

No. Unused inputs may be tied directly to VCC or GND. The device has no internal pull resistors, but its high input impedance (<1µA leakage) and power-down protection make externally terminated inputs unnecessary-floating inputs are prohibited per design rules to avoid metastability and increased ICC.

Is the SOT23-8L package of the 74V2G02STR RoHS-compliant and halogen-free?

Yes. Per STMicroelectronics' official product change notice PCN 19-0127, all 74V2G02STR devices manufactured after Q2 2019 are RoHS-compliant and halogen-free, meeting IEC 61249-2-21 and JEDEC JS709C requirements, with full material declarations available via ST's Quality Portal.
