Texas Instruments SN74LVC2G34 Dual Buffer Gate IC SOT-23-6

The Texas Instruments SN74LVC2G34 Dual Buffer Gate IC is a dual buffer gate integrated circuit in a SOT-23-6 package, designed for signal conditioning across a 1.65 V to 5.5 V VCC range with a 4.1 ns propagation delay at 3.3 V.

Overview

The device performs the Boolean function Y = A in positive logic, making it suitable for maintaining signal integrity in digital systems. It is fully specified for partial-power-down applications using IOFF, which disables the outputs when the device is powered down to prevent damaging current backflow. This supports live insertion, partial-power-down modes and back-drive protection, making it suitable for hot-swappable applications and systems where power sequencing is critical.

Key Features

• Dual buffer gate with Boolean function Y = A in positive logic
• Supply voltage (VCC) range of 1.65 V to 5.5 V
• Inputs accept voltages up to 5.5 V
• Functions as a down translator, translating signals from up to 5.5 V down to the lower VCC level
• Latch-up performance exceeding 250 mA per JESD 17
• Propagation delay (tpd) of 4.1 ns at 3.3 V
• Low ICC consumption of 10 µA
• Output drive of ±24 mA at 3.3 V
• Controlled output switching noise, with VOLP (output ground bounce) and VOHV (output VOH undershoot) parameters specified

Applications

This buffer IC is suitable for the following application areas:

• Industrial automation and control systems
• Signal processing units
• Audio and imaging equipment
• Video and vision systems
• Consumer electronics

This component suits designs that require reliable signal conditioning and level shifting across mixed-voltage digital systems.
