{"product_id":"snj5407fk","title":"SNJ5407FK","description":"\u003cp\u003eThe SNJ5407FK is a robust non-inverting hex buffer from Texas Instruments, featuring open-collector outputs for high-voltage switching applications. With six independent channels, each capable of sinking 30mA, it can directly drive relays, lamps, and LEDs. The device operates from a 4.5V to 5.5V supply, while the output stage can handle voltages up to 30V via an external pull-up resistor. Packaged in a 20-CLCC ceramic package, it is designed for military and aerospace applications, functioning reliably across the full -55°C to 125°C temperature range. This buffer is essential for interfacing 5V logic with higher-voltage peripherals.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHigh-Voltage Output Capability (30V): Allows direct control of loads that operate at voltages far exceeding the logic supply.\u003c\/li\u003e\n\u003cli\u003eHigh Sink Current (30mA): Provides sufficient drive for relays, solenoids, and high-intensity LEDs.\u003c\/li\u003e\n\u003cli\u003eOpen-Collector Design: Enables wired-OR logic and flexible level shifting to any desired voltage.\u003c\/li\u003e\n\u003cli\u003eMilitary Temperature Range: Ensures dependable performance in extreme thermal conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDriving High-Voltage Displays\u003c\/h3\u003e\u003cp\u003eIn avionics cockpit displays, the SNJ5407FK's open-collector outputs can switch up to 30V, enabling direct control of segmented VFD or incandescent indicators without additional driver transistors.\u003c\/p\u003e\u003ch3\u003eInterfacing with Relay Coils\u003c\/h3\u003e\u003cp\u003eFor industrial control systems, this buffer can sink the 30mA required by many relay coils.
