STMicroelectronics 74V2G00STR

Overview

74V2G00STR from STMicroelectronics is a dual 2-input NAND gate IC in SOT23-8L package, operating from 2V to 5.5V supply, with typical propagation delay of 3.7ns at 5V, symmetrical output drive (±8mA), 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 74V2G00STR datasheet, 74V2G00STR pinout, 74V2G00STR application, or 74V2G00STR equivalent, key selection criteria include its dual-gate configuration, power-down protected inputs, rail-to-rail input voltage acceptance (0–7V), and guaranteed noise immunity (28% VCC min) for industrial control and legacy interface bridging.

Technical Context

This device implements two independent CMOS NAND gates using sub-micron C2MOS technology with three-stage buffered outputs, delivering balanced tPLH/tPHL delays and stable switching across temperature (−55°C to +125°C). Its input structure supports overvoltage tolerance and power-down protection without external clamping.

Designed for mixed-supply systems, it accepts VI from 0 to 7V regardless of VCC (2–5.5V), enabling direct interfacing between 5V TTL and 3.3V/2.5V logic domains while maintaining guaranteed VOH/VOL levels at ±8mA loads.

FAQ

Can 74V2G00STR be used with VCC = 0V while inputs are active?

Yes. Its power-down protection allows inputs to accept 0–7V signals even when VCC = 0V, with no reverse current flow or damage. This feature enables safe hot-plug operation and partial power-down modes in modular systems without disabling upstream signal sources.

What is the maximum capacitive load this device can drive reliably?

The 74V2G00STR is characterized up to 50pF load capacitance with guaranteed AC performance (tPLH/tPHL). Driving >50pF may increase propagation delay and cause marginal timing in high-speed paths; for heavier loads, add a buffer stage or verify timing margins using the CPD = 19pF parameter in power consumption calculations.

Does this part support 1.8V logic operation?

No. The minimum recommended VCC is 2.0V per datasheet specifications. At 1.8V, VIH/VIL thresholds and output drive strength fall outside guaranteed limits, risking logic misinterpretation and insufficient fan-out-use 74AUP2G00 or similar for true 1.8V operation.

How does the 28% VCC noise immunity translate to actual voltage margin at 3.3V supply?

At VCC = 3.3V, VNIH and VNIL are guaranteed ≥0.924V (28% of 3.3V), meaning input transitions are rejected unless they exceed ±0.924V from the respective logic threshold. This provides ≥0.9V noise margin against coupled transients in electrically noisy motor control or power supply environments.
