The CD4051BEX is a single 8-channel analog multiplexer/demultiplexer manufactured by RCA.
Key Specifications:
- Supply Voltage Range (VDD to VSS): 3V to 20V
- Analog Signal Range (VEE to VDD): ±5V (with ±5V supply)
- Low ON Resistance: 125Ω (typical at VDD - VEE = 15V)
- Low OFF Leakage Current: ±100pA (typical at VDD - VEE = 18V)
- Logic Level Conversion: Allows digital signals (0V to 5V) to control analog signals (up to ±5V)
- Break-Before-Make Switching: Prevents signal overlap during channel switching
- Operating Temperature Range: -55°C to +125°C
Features:
- 8-Channel Multiplexer/Demultiplexer: Can select one of eight input/output signals
- 3-Bit Binary Address Control: Uses three digital inputs (A, B, C) to select channels
- Inhibit (INH) Pin: Disables all channels when set high
- Wide Supply Voltage Range: Compatible with both TTL and CMOS logic levels
- Low Power Consumption: Ideal for battery-operated applications
Applications:
- Analog signal switching
- Data acquisition systems
- Audio and video routing
- Communication systems
The CD4051BEX is a robust, general-purpose analog switch suitable for a variety of signal routing applications.
