STMicroelectronics 74V2T04STR

Overview

74V2T04STR from STMicroelectronics is a triple inverter IC in SOT23-8L package, designed for high-speed 5V logic interfacing with 4.7ns typical propagation delay, ±8mA symmetrical output drive, and 4.5–5.5V operating range. It enables level-shifting between 5V and 3V systems while providing input overvoltage tolerance up to 7V.

For engineers reviewing the 74V2T04STR datasheet, 74V2T04STR pinout, 74V2T04STR application, or 74V2T04STR equivalent, key selection criteria include propagation delay matching, input overvoltage robustness, power-down protection, and symmetrical drive capability in space-constrained 5V logic designs.

Technical Context

This device implements three independent CMOS inverter stages with buffered outputs, fabricated using sub-micron C2MOS technology. Its input structure accepts 0–7V regardless of VCC, enabling safe hot-plug and mixed-voltage interface operation without external clamping.

The symmetrical output impedance (|IOH| = IOL ≥ 8mA at VCC = 4.5V) and balanced tPLH/tPHL delays ensure consistent rise/fall timing across logic transitions, critical for noise-sensitive clock distribution and data inversion paths.

FAQ

Can the 74V2T04STR safely interface a 3.3V microcontroller output to a 5V load?

No - the 74V2T04STR operates only from a 4.5–5.5V supply and does not translate down to 3.3V logic levels. Its inputs accept 0–7V, but its outputs swing rail-to-rail between GND and VCC. To drive a 3.3V load, an additional level-shifter or resistor divider is required on the output side.

Does the 74V2T04STR support hot-plug operation when VCC is unpowered?

Yes - its inputs feature power-down protection and tolerate 0–7V regardless of VCC state. When VCC = 0V, inputs remain high-impedance and non-damaging, allowing safe connection of live signals prior to system power-up, a key requirement in modular backplane and field-replaceable unit designs.

What is the maximum capacitive load this device can drive while maintaining 4.7ns propagation delay?

The 4.7ns typical tPD is specified with CL = 15pF. At CL = 50pF, tPD increases to 5.5ns (typ). For designs requiring ≤5ns delay, total load capacitance - including PCB trace, probe, and driven gate input - must be held to ≤20pF to maintain timing margin across temperature and voltage extremes.

Is the SOT23-8L package of the 74V2T04STR compatible with standard pick-and-place equipment?

Yes - the SOT23-8L package conforms to JEDEC MO-178AB mechanical standards, with 0.65mm pin pitch, 1.95mm lead spacing, and coplanarity ≤0.1mm. It is supported by mainstream placement machines (e.g., Fuji NXT, Yamaha YSM20) using standard 0805–1206 nozzle tooling and vision calibration profiles.
