Overview
The SNJ5407FK, part of the SN74x7 series, is a TTL hex buffer and driver produced by Texas Instruments. This device is characterized by its high-voltage open-collector outputs, making it suitable for interfacing with high-level circuits such as MOS or for driving high-current loads like lamps or relays. It is also designed to act as a buffer for driving TTL inputs. The SNJ5407FK is part of the military-grade SNJ series, ensuring compliance with stringent military standards like MIL-PRF-38535.
