The MC14503BDG from onsemi is a hex non-inverting buffer with 3-state outputs, part of the 4000B CMOS family. It operates from 3V to 18V, making it one of the most versatile buffers for high-voltage logic systems. With 14.1mA sink and 25mA source current, it can drive relays, LEDs, and long bus lines. Its wide temperature range (-55°C to 125°C) suits automotive and military applications. The 16-SOIC package is compact and reliable.
- Ultra-Wide Voltage Range (3V-18V): Compatible with 5V, 12V, and 15V logic systems.
- High Source Current (25mA): Drives relays, solenoids, and LEDs directly.
- Extended Temperature Range (-55°C to 125°C): Suitable for harsh environments.
- Low Power CMOS: Ideal for battery-powered devices.
High-Voltage Industrial Logic
With a 3V to 18V supply range, the MC14503BDG is perfect for industrial control systems operating at 12V or 15V logic levels, common in PLCs and motor controllers.
Battery-Powered Instrumentation
Its low power consumption and wide voltage range make it ideal for portable instruments running on 9V batteries, buffering sensor signals to a display or ADC.
Automotive 12V Systems
Directly interface with 12V automotive signals without level shifting, buffering ignition and sensor signals to the ECU.
Relay and Solenoid Drivers
The 14.1mA sink / 25mA source capability allows direct driving of small relays and solenoids in vending machines and appliances.
Analog Switch Control
Use this buffer to drive the control inputs of analog multiplexers (e.g., CD4051) in data acquisition systems, ensuring clean switching.
Legacy 5V System Expansion
In older 5V-only systems, this buffer provides robust 3-state expansion for memory or I/O buses without worrying about overvoltage damage.
