SN74LVTH125PW

SN74LVTH125PW Description

The SN74LVTH125PW from Texas Instruments is a high-performance quad bus buffer gate designed for 3.3V VCC operation, featuring non-inverting outputs and tri-state functionality. Housed in a 14-pin TSSOP package, this device is optimized for low-voltage applications (2.7V to 3.6V) while delivering robust output drive capability (32mA high/64mA low). As part of the 74LVTH series, it combines LVTTL compatibility with 5V-tolerant inputs, making it ideal for mixed-voltage systems. Its surface-mount design and RoHS3 compliance ensure environmental and regulatory suitability for modern electronics.

SN74LVTH125PW Features

• Quad Non-Inverting Buffer: Four independent 1-bit buffers with tri-state outputs for bus isolation.
• Wide Operating Voltage: Supports 2.7V to 3.6V, compatible with 3.3V logic systems.
• High Drive Strength: 32mA (high)/64mA (low) output current for driving heavy loads.
• 5V-Tolerant Inputs: Allows interfacing with 5V logic without external level shifters.
• Low Power Consumption: LVTH technology reduces static and dynamic power dissipation.
• Robust Packaging: 14-TSSOP with MSL1 (Unlimited) moisture sensitivity, suitable for automated assembly.
• Enhanced ESD Protection: Exceeds 2000V HBM for improved reliability.

SN74LVTH125PW Applications
