The SN74CB3Q3305DCUR is a specific part number for a 1-bit dual-supply, dual SPDT (Single-Pole, Double-Throw) analog switch/multiplexer IC (Integrated Circuit) manufactured by Texas Instruments. This IC is designed for analog and digital signal routing and switching applications.
Key Features:
- Dual-SPDT Analog Switch: The IC includes two independent SPDT analog switches, each capable of routing a single input signal to one of two output channels.
- Dual Supply Voltage Compatibility: It can operate with two different supply voltage levels (VCCA and VCCB), making it suitable for interfacing between components or subsystems operating at different voltage levels.
- Low On-Resistance: The IC typically features low on-resistance, ensuring minimal signal attenuation when switching.
- Wide Voltage Range: The IC can handle a wide voltage range, typically from 1.65V to 5.5V, making it versatile for various voltage levels.
- 3-State Outputs: It provides 3-state outputs, allowing you to control whether the outputs are actively driving signals or in a high-impedance state.
