Single-gate buffer for mixed-voltage and high-temp boards
The SN74LVC1G34DBVTE4: It delivers a push-pull output with 32mA source and sink capability, making it a straightforward choice for signal buffering, line driving, or fan-out expansion in mixed-voltage systems.
At 125°C junction temperature, the drive current is still within spec, but the thermal derating on the package limits total power dissipation — keep the output switching frequency under a few MHz if driving heavy loads at high temperature.
The base product number 74LVC1G34 is widely used across the industry, so second-sourcing from other 74LVC1G34 suppliers is straightforward — just verify the package code (DBV = SOT-23-5) and the tape-and-reel suffix match your pick-and-place setup.
Package and footprint — SOT-23-5
The device comes in a SOT-23-5 package (also designated SC-74A), a five-pin surface-mount package with a 0.95 mm pitch. The footprint is standard across the 74LVC1Gxx single-gate family, so swapping between a buffer, inverter, or AND gate in the same package requires no board layout change.
