STMicroelectronics 74V2G08STR

Overview

74V2G08STR from STMicroelectronics is a dual 2-input AND gate in high-speed CMOS technology, operating from 2V to 5.5V supply, with typical propagation delay of 3.8ns at 5V, symmetrical output drive (±8mA), and input tolerance up to 7V independent of VCC. It enables level-shifting between 5V and 3V logic domains in compact portable and mixed-voltage digital systems.

For engineers reviewing the 74V2G08STR datasheet, 74V2G08STR pinout, 74V2G08STR application, or 74V2G08STR equivalent, key selection criteria include its dual-gate logic function, SOT23-8L package footprint, rail-to-rail input voltage tolerance (0–7V), low quiescent current (1µA max), and balanced tPLH/tPHL timing behavior.

Technical Context

This device implements two independent AND gates using sub-micron C2MOS process with buffered outputs, delivering high noise immunity (VNIH/VNIL ≥ 28% VCC) and latch-up robustness. Its inputs feature power-down protection and accept voltages beyond VCC (up to 7V), enabling safe interfacing across differing supply domains.

The internal two-stage buffer architecture ensures stable output transitions and symmetrical rise/fall drive capability (|IOH| = IOL ≥ 8mA at VCC = 4.5V), while propagation delays remain closely matched (tPLH ≅ tPHL) across temperature and voltage ranges.

FAQ

Can 74V2G08STR operate with VCC = 2.5V while accepting 5V inputs?

Yes. The device is explicitly rated for input voltages from −0.5V to +7.0V regardless of VCC, including operation at 2.5V supply. This enables direct interfacing of 5V signals into 2.5V logic domains without external level-shifting components or risk of latch-up.

What is the maximum recommended capacitive load for reliable 3.8ns propagation delay?

The 3.8ns typical propagation delay is specified at CL = 15pF and VCC = 5.0V. For loads exceeding 15pF, delay increases linearly - e.g., at 50pF, tPD rises to 4.6ns. Maintain CL ≤ 30pF for sub-5ns timing budgets in high-speed routing.

Does 74V2G08STR require pull-up or pull-down resistors on unused inputs?

No. Unused inputs may be left floating due to internal input protection circuitry and guaranteed noise margins (VNIH/VNIL ≥ 28% VCC). However, tying them to VCC or GND is preferred for deterministic logic state and EMI reduction in high-noise environments.

Is the SOT23-8L package RoHS-compliant and lead-free?

Yes. Per STMicroelectronics' official product documentation, the 74V2G08STR in SOT23-8L packaging is RoHS-compliant and fully lead-free, meeting JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) requirements for standard surface-mount assembly.
