CD4051BQPWR Analog Multiplexer/Demultiplexer by Texas Instruments

The CD4051BQPWR is a versatile single 8-channel multiplexer/demultiplexer integrated circuit designed and manufactured by Texas Instruments. This high-performance CMOS device is part of the CD4000 series and is well-suited for a wide range of analog and digital applications, including signal gating, chopping, modulation or demodulation (modem), and signal multiplexing for analog-to-digital conversion systems.

This multiplexer/demultiplexer IC provides industry-standard features and is designed to handle both analog and digital signals. The device allows for the selection of one of eight channels to be turned on and connects that channel to a common output or input, depending on the mode of operation. The CD4051BQPWR can handle signal frequencies up to 20MHz and has a typical on-state resistance of 240 ohms, making it highly efficient for various signal processing tasks.

The CD4051BQPWR is offered in a TSSOP-16 (Thin Shrink Small Outline Package) which is ideal for space-constrained applications. The device operates over a broad voltage range from 3V to 18V, providing flexibility for use in systems with different power levels. Moreover, it features low "ON" resistance and low "OFF" leakage current, ensuring minimal signal distortion and power loss during operation.

Key features of the CD4051BQPWR include:

• Single 8-Channel Multiplexing/Demultiplexing Capability
• Binary Address Decoding
• Low ON Resistance: 240Ω (typical) at VDD - VEE = 10V
• Wide Analog Input Voltage Range: ±5V (peak)
• Low Crosstalk between Switches
• Individual Switch Controls
• Wide Operating Temperature Range: -55°C to 125°C
• Compatible with TTL and CMOS Levels

Applications for the CD4051BQPWR are diverse and include data acquisition systems, analog signal routing, communication systems, and avionics. Its reliability and functional flexibility make it an excellent choice for designers looking to add efficient channel selection or signal routing capabilities to their electronic projects or products.
