STMicroelectronics 74V1G00STR

Overview

74V1G00STR from STMicroelectronics is a single 2-input NAND gate in SOT23-5L package, operating from 2V to 5.5V supply, with 3.7ns 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 74V1G00STR datasheet, 74V1G00STR pinout, 74V1G00STR application, or 74V1G00STR equivalent, key selection criteria include propagation delay matching, input overvoltage tolerance, rail-to-rail output swing under load, and SOT23-5L thermal and board-space constraints in space-constrained digital control circuits.

Technical Context

This device implements a three-stage CMOS NAND gate with integrated input buffer and output driver, fabricated using sub-micron C2MOS technology. Its power-down protection allows safe 0–7V input voltage regardless of VCC, and symmetrical |IOH| = |IOL| ≥ 8mA ensures matched rise/fall times (tPLH ≅ tPHL).

The logic core supports wide VCC operation (2–5.5V) with guaranteed VIH/VIL thresholds referenced to VCC (0.7VCC/0.3VCC), and exhibits high noise immunity (VNIH = VNIL ≥ 28% VCC), making it suitable for noisy industrial control signal conditioning and mixed-supply interface buffering.

FAQ

Can 74V1G00STR safely interface a 5V sensor output to a 3.3V microcontroller input?

Yes. Its inputs tolerate 0–7V regardless of VCC, so a 5V sensor signal applied to Pin 1 or 2 while VCC = 3.3V causes no damage and meets VIH = 0.7×3.3V = 2.31V, ensuring reliable logic-high recognition without external components.

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

The AC specifications define tPD with CL = 15pF and CL = 50pF loads. At VCC = 5.0V, tPD remains within spec (≤7.5ns max) up to 50pF. Driving >50pF increases delay nonlinearly and may degrade edge rate; for >100pF, consider buffer staging or lower-capacitance routing.

Does 74V1G00STR require external pull-up or pull-down resistors on unused inputs?

No. Unused inputs must be tied to VCC or GND-floating inputs are prohibited due to CMOS susceptibility to noise-induced shoot-through current. The device has no internal pull-ups; external termination is mandatory for defined logic state and to prevent increased ICC and potential malfunction.

How does the 74V1G00STR's latch-up immunity compare to standard 74HC logic?

It features improved latch-up immunity per design-achieved via sub-micron C2MOS process and optimized well structures-allowing survival under transient overvoltage events that would trigger latch-up in older 74HC devices. Absolute maximum ratings confirm safe operation up to 7V on inputs even during power-down states.
