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

The Texas Instruments SN74LVC2G34DBVR is a dual buffer gate integrated circuit designed for reliable signal conditioning across a broad voltage range. Operating from 1.65V to 5.5V VCC, this device performs the Boolean function Y = A in positive logic, making it an essential component for maintaining signal integrity in digital systems.

A key feature is its full specification for partial-power-down applications using IOFF. This protective circuitry disables the outputs when the device is powered down, preventing damaging current backflow and offering robust support for live insertion, partial-power-down modes, and back-drive protection. This makes it exceptionally suitable for hot-swappable applications and systems where power sequencing is critical.

The device also functions effectively as a down translator, capable of translating input signals from up to 5.5V down to the lower VCC level, providing essential level-shifting capabilities in mixed-voltage environments. It boasts strong latch-up performance, exceeding 250mA per JESD 17 standards, and its inputs can accept voltages up to 5.5V, enhancing its versatility and resilience.

Performance is characterised by a fast 4.1ns propagation delay (tpd) at 3.3V, ensuring swift signal processing. It maintains excellent power efficiency with a low ICC consumption of just 10µA. The output drive is a robust ±24mA at 3.3V, and it features controlled output switching noise with parameters like VOLP (output ground bounce) and VOHV (output VOH undershoot) specified. Furthermore, it is a green product, manufactured with no antimony or bromine (Sb/Br).
