MC14504B

The MC14504B is a CMOS 8-stage inverting buffer/driver manufactured by onsemi, designed for high-speed signal conditioning and level shifting applications. It features eight independent inverters, each capable of driving up to 100 mA of load current, making it suitable for interfacing between logic families with different voltage levels or driving external components such as LEDs, relays, or motors. The device operates over a wide supply voltage range from 3 V to 15 V, providing flexibility in power supply design across various systems. Each stage of the MC14504B offers high input impedance and low output impedance, ensuring minimal loading effects on preceding circuits while maintaining strong drive capability. Its propagation delay is typically under 100 ns at a 5 V supply, enabling efficient performance in timing-critical applications like digital communication interfaces or clock distribution networks. The IC also exhibits low quiescent current—less than 1 μA per stage at 5 V—which enhances energy efficiency in battery-powered or portable devices. The MC14504B is packaged in a 16-pin DIP (Dual In-line Package), offering ease of integration into through-hole PCB designs. It includes built-in protection against electrostatic discharge (ESD) and features guaranteed noise immunity, making it robust in industrial environments where electromagnetic interference (EMI) may be present. Additionally, the device maintains stable operation across a broad temperature range—from -40°C to +85°C—supporting its use in both consumer and industrial electronics. Common applications include data buffering in microprocessor systems, signal inversion in logic circuits, multiplexer/demultiplexer control, and driving high-current loads such as solenoids or small actuators. It is often used in instrumentation, automotive control modules, and consumer appliances where reliable, low-power logic level translation is required. Due to its versatility and ruggedness, the MC14504B serves as a fundamental building block in mixed-signal and digital systems where signal integrity and drive strength are critical.
