BU4053BC

BU4053BC Description

The BU4053BC from ROHM Semiconductor is a triple SPDT (Single Pole Double Throw) analog switch designed for signal routing and multiplexing/demultiplexing in electronic circuits. Housed in a 16-pin DIP (Dual Inline Package), this IC features low leakage current (max 300nA), low on-state resistance (max 160Ω), and minimal channel capacitance (10pF), ensuring high signal integrity and minimal distortion. Operating within a wide voltage range (3V to 18V), it is suitable for both low and high-voltage applications. Though marked as Obsolete, it remains a reliable choice for legacy designs due to its ROHS3 compliance and REACH-unaffected status.

BU4053BC Features

• Triple SPDT Configuration: Three independent 2:1 multiplexers/demultiplexers in a single package.
• Low Power Consumption: Leakage current limited to 300nA (max), ideal for battery-operated devices.
• Fast Switching: Low channel capacitance (10pF) ensures minimal signal delay.
• Wide Voltage Range: Supports 3V to 18V single-supply operation, accommodating diverse system requirements.
• Robust Packaging: Through-hole 16DIP for easy prototyping and rugged applications.
• Compliance: ROHS3 compliant and REACH unaffected, meeting environmental standards.

BU4053BC Applications

• Audio/Video Signal Routing: Used in mixers, amplifiers, and AV switches for clean signal transmission.
• Data Acquisition Systems: Multiplexes analog sensor inputs in industrial and medical equipment.
• Test & Measurement Equipment: Enables flexible signal path switching in oscilloscopes and logic analyzers.
• Battery-Powered Devices: Low leakage current makes it suitable for portable electronics.
• Legacy System Maintenance: Ideal for servicing older designs requiring through-hole components.

Conclusion of BU4053BC

The BU4053BC is a versatile, high-performance analog switch with low distortion, wide voltage tolerance, and reliable multiplexing capabilities.
