74V1T125STR

74V1T125STR Description

The 74V1T125STR is a single-bit non-inverting buffer from STMicroelectronics, designed for high-performance digital signal management in low-voltage applications. Operating within a 4.5V to 5.5V supply range, this device ensures reliable signal integrity with balanced output drive capabilities (8mA sink/source current). Packaged in a compact SOT23-5 form factor and delivered in Tape & Reel (TR), it is optimized for space-constrained, high-density PCB designs. As part of the 74V series, it combines low power consumption with robust performance, making it suitable for both industrial and consumer electronics.

74V1T125STR Features

• Single-Channel Non-Inverting Buffer: Ensures signal fidelity without phase reversal.
• Wide Operating Voltage (4.5V–5.5V): Compatible with standard 5V logic systems.
• High Output Drive (8mA): Supports moderate load conditions without external amplification.
• Surface-Mount SOT23-5 Package: Ideal for miniaturized designs.
• RoHS3 & REACH Compliant: Meets environmental and safety standards.
• Low Moisture Sensitivity (MSL 1): Suitable for extended storage and handling.
• Obsolete Status: Verify availability for new designs; ideal for legacy system maintenance.

74V1T125STR Applications

• Signal Conditioning: Cleans up noisy digital signals in sensor interfaces or communication lines.
