The CD4053B is a versatile Triple 2-Channel Analog Multiplexer/Demultiplexer Integrated Circuit designed and manufactured by Texas Instruments. This IC is part of their 4000 series CMOS range, renowned for its robustness and reliability in a wide array of electronic applications.

This particular model, the CD4053B, features three separate digital multiplexers/demultiplexers with common select and reset inputs. Each multiplexer/demultiplexer has two independent inputs/outputs (Y and Z) and a common input/output (X). The device operates as a digital multiplexer when the digital control signals select data from one of the two inputs (Y or Z) to output at X. Conversely, it operates as a demultiplexer when it channels a single input (X) to one of the two outputs (Y or Z) based on the control signals.

The CD4053B can handle both analog and digital signals, allowing it to pass signals ranging from the negative supply voltage (V_EE) to the positive supply voltage (V_DD). This feature makes it an excellent choice for various signal routing applications. It is characterized for operation from -55°C to 125°C, ensuring reliable performance in a broad range of environmental conditions.

Key features of the CD4053B include:

• Low ON resistance (125 Ω typical at V_DD - V_EE = 10V)
• Low Crosstalk between switches
• High ON/OFF Output Voltage Ratio
• Wide range of digital and analog signal levels
• Low Noise
• 15V Digital or ±7.5V Peak-to-Peak Switching
• Matched Switch Characteristics
• High Degree of Linearity
• Extremely Low Off-Channel Leakage

Applications for the CD4053B are diverse and include analog signal switching/multiplexing, digital signal switching/multiplexing, signal gating, chopper applications, and more. With its ability to handle multiple signal types and its high degree of reliability, the CD4053B from Texas Instruments is an essential component for designers and engineers who require a flexible and dependable multiplexing solution.
