The MC14503BDR2G from onsemi is a dual non-inverting buffer featuring 3-state outputs and a wide operating voltage range of 3V to 18V. Built on the 4000B CMOS logic family, it delivers high noise immunity and low power dissipation. Each of its two channels can source 25mA or sink 14.1mA, making it suitable for driving buses, LEDs, or other logic families. The 16-SOIC package is ideal for space-constrained industrial and consumer applications requiring reliable signal buffering and isolation.
- Wide 3V to 18V Supply Range: Compatible with 5V, 12V, and 15V systems, simplifying multi-voltage designs.
- 3-State Outputs: Enables bus sharing and peripheral isolation, preventing data conflicts.
- High Output Current (25mA Source / 14.1mA Sink): Can drive TTL loads and LEDs directly without extra drivers.
- 4000B CMOS Logic: Offers very low power consumption and high noise immunity for industrial environments.
Bus Line Driving
With 3-state outputs and a wide 3V-18V supply, the MC14503BDR2G can drive long bus lines in industrial control systems, preventing signal degradation and allowing multiple devices to share the same data path.
Level Shifting for Mixed-Voltage Systems
Its wide voltage range enables simple level shifting between 5V and 12V or 15V logic sections, reducing the need for external level translators in multi-voltage designs.
Memory Address Buffering
In microprocessor systems, this buffer isolates the CPU address lines from high-capacitance memory arrays, improving signal integrity and timing margins.
Peripheral Isolation
Use the 3-state feature to disconnect peripherals from the main data bus when not in use, reducing power consumption and preventing bus contention.
High-Voltage Industrial Logic
For PLCs and motor controllers operating at 12V or 15V logic, this 4000B-series buffer provides robust, noise-immune signal buffering in harsh environments.
CMOS-to-TTL Interfacing
With its high output current (14.1mA sink, 25mA source), it can drive TTL loads directly, simplifying mixed-logic-family designs.
