SNJ5406FK

Buffers, Drivers, Receivers, Transceivers Overview

The SNJ5406FK is a military-grade hex inverter buffer and driver featuring open-collector high-voltage outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -55°C to +125°C. The device provides a minimum breakdown voltage of 30 V on its outputs, with a maximum sink current capability of 30 mA. Propagation delay times are specified as 10 ns (typical) for low-to-high transitions and 23 ns (maximum) for high-to-low transitions at 5 V.
