STMicroelectronics 74V2T08STR

Overview

74V2T08STR from STMicroelectronics is a dual 2-input AND gate IC in SOT23-8L package, operating at 4.5–5.5 V with 3.8 ns typical propagation delay (VCC = 5 V), ±8 mA symmetrical output drive, and 1 µA max quiescent current at 25°C - used for high-speed logic interfacing between 5 V and 3 V systems.

For engineers reviewing the 74V2T08STR datasheet, 74V2T08STR pinout, 74V2T08STR application, or 74V2T08STR equivalent, key selection criteria include propagation delay matching, input voltage tolerance (0–7 V), power-down input protection, symmetrical drive strength, and SOT23-8L board space constraints.

Technical Context

This device implements two independent CMOS AND gates using sub-micron C2MOS technology with buffered outputs, delivering balanced tPLH/tPHL delays and high noise immunity. Input structures tolerate 0–7 V regardless of VCC, enabling robust level-shifting operation.

It features power-down protection on all inputs/outputs, allowing safe operation during supply sequencing or partial power loss. The internal circuit includes two-stage buffering to stabilize output transitions and suppress ringing under capacitive loads.

FAQ

Can the 74V2T08STR operate with a 3.3 V supply?

No - the 74V2T08STR is specified only for 4.5–5.5 V operation per its Recommended Operating Conditions. At 3.3 V, VIH/VIL thresholds become unmet, and output drive falls below specification. For 3.3 V systems, consider SN74LVC2G08DBVR instead.

Does the 74V2T08STR require external pull-up or pull-down resistors on unused inputs?

No - unused inputs may be left unconnected due to built-in power-down protection and high-impedance input structure. However, tying them to VCC or GND is recommended to prevent noise coupling in high-noise environments.

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

The AC Electrical Characteristics specify CL = 15 pF and 50 pF test conditions. With 8 mA drive capability and 3.8 ns tPD at 15 pF, the device reliably drives ≤30 pF loads while maintaining timing integrity; beyond that, propagation delay increases nonlinearly.

Is the SOT23-8L package thermally enhanced or does it require heatsinking?

The SOT23-8L package has no thermal pad or heatsink provision. Its 1 µA max ICC results in negligible self-heating (<0.1 mW at 5 V), so no heatsinking is required - even at +125°C ambient, junction temperature remains within safe limits under normal operation.
