STMicroelectronics 74V1T00STR

Overview

74V1T00STR from STMicroelectronics is a single 2-input NAND gate in SOT23-5L package, operating at 4.5–5.5 V with 5.0 ns typical propagation delay, ±8 mA output drive, and input tolerance up to 7 V independent of supply. It enables 5 V-to-3 V interfacing in space-constrained logic control circuits.

For engineers reviewing the 74V1T00STR datasheet, 74V1T00STR pinout, 74V1T00STR application, or 74V1T00STR equivalent, key selection criteria include input overvoltage tolerance, symmetrical output drive, power-down protection, and sub-5 ns propagation delay under 5 V operation.

Technical Context

This device implements a three-stage CMOS NAND gate with buffered output, fabricated using sub-micron C2MOS technology. Its input structure accepts 0–7 V regardless of VCC, enabling robust level-shifting between 5 V and 3 V domains without external biasing.

The symmetrical output impedance (|IOH| = IOL ≥ 8 mA at VCC = 4.5 V) and balanced tPLH ≅ tPHL ensure minimal duty-cycle distortion in clocked or data-path applications. Quiescent ICC ≤ 1 µA supports low-power standby modes in battery-aware systems.

FAQ

Can the 74V1T00STR operate with VCC = 3.3 V?

No. The 74V1T00STR is specified only for VCC = 4.5 V to 5.5 V per its Recommended Operating Conditions table. At 3.3 V, it fails to meet VIH/VIL thresholds and may not function reliably. For 3.3 V systems, consider the 74LVC1G00 or 74AHC1G00 families instead.

Does the 74V1T00STR require external pull-up or pull-down resistors on inputs?

No. Inputs are internally protected with power-down circuitry and do not float when unconnected. However, for deterministic logic states in unused configurations, STMicroelectronics recommends tying unused inputs to VCC or GND-not left floating-to prevent noise-induced switching and excess current draw.

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

The AC Electrical Characteristics specify performance up to CL = 50 pF with tPLH/tPHL ≤ 9.0 ns at −55°C to +125°C. Driving >50 pF increases propagation delay nonlinearly and may cause marginal timing in high-speed applications; for heavier loads, add a buffer stage or select a higher-drive logic family.

Is the 74V1T00STR pin-compatible with other SOT23-5 logic gates?

Yes-pinout matches JEDEC-standard SOT23-5 for single-gate logic: Pin 1 = A, Pin 2 = B, Pin 3 = GND, Pin 4 = Y, Pin 5 = VCC. This allows mechanical substitution with devices like SN74LVC1G00DBVR or 74AHC1G00SE-7, though electrical compatibility (e.g., input voltage range, drive strength) must be verified per application.
