STMicroelectronics 74V1T08CTR

Overview

74V1T08CTR from STMicroelectronics is a single 2-input AND gate in SOT323-5L package, operating at 4.5–5.5 V with 4.7 ns typical propagation delay, ±8 mA symmetrical output drive, and input tolerance up to 7 V independent of supply. It enables level-shifting between 5 V and 3 V logic domains in compact interface circuits.

For engineers reviewing the 74V1T08CTR datasheet, 74V1T08CTR pinout, 74V1T08CTR application, or 74V1T08CTR equivalent, key selection criteria include propagation delay matching, input overvoltage tolerance, symmetrical drive strength, and SOT323-5L footprint compatibility in space-constrained 5 V logic systems.

Technical Context

This device implements a two-stage buffered CMOS AND gate using sub-micron C2MOS technology, delivering high noise immunity and stable rail-to-rail output swing. Its input structure supports 0–7 V input voltage regardless of VCC, enabling robust interfacing across mixed-voltage subsystems.

The output stage provides matched |IOH| = |IOL| ≥ 8 mA at VCC = 4.5 V, ensuring balanced rise/fall times (tPLH ≅ tPHL), while power-down protection prevents back-driving damage when VCC = 0 V.

FAQ

Can 74V1T08CTR operate with VCC = 3.3 V?

No. The 74V1T08CTR is specified only for 4.5–5.5 V operation per its Recommended Operating Conditions table. At 3.3 V, VIH/VIL thresholds and output drive fall outside guaranteed specifications, risking logic misreads and weak drive strength. Use 74LVC1G08 or 74AUP1G08 for 3.3 V systems.

Does 74V1T08CTR require external pull-up or pull-down resistors on inputs?

No. Inputs are internally protected and do not float to undefined states. However, for unused inputs, tie them HIGH or LOW via direct connection to VCC or GND - never leave open - to prevent noise-induced switching and excess ICC. No external resistors are needed for functional operation.

What is the maximum capacitive load CL supported at full speed?

The AC Electrical Characteristics table specifies tPLH/tPHL test conditions at CL = 15 pF and CL = 50 pF. At 50 pF, max propagation delay is 9.5 ns over temperature. For reliable 4.7 ns typical performance, keep total load ≤15 pF - including PCB trace capacitance, probe effects, and downstream input capacitance.

Is 74V1T08CTR pin-compatible with other SOT323-5L AND gates?

Pinout matches standard SOT323-5L logic gate orientation (1A, 1B, GND, 1Y, VCC), but electrical behavior differs. Substituting 74LVC1G08 or 74AUP1G08 risks input overvoltage damage or incorrect logic thresholds due to absence of 7 V tolerance and different VIH/VIL specs - mechanical compatibility does not imply functional interchangeability.
