Product Overview: SN74AUC1G66DBVR - Texas Instruments

The SN74AUC1G66DBVR from Texas Instruments is a high-performance, single-pole, single-throw (SPST) analog switch that is designed to deliver both high speed and low power operation. This switch is a part of the ultra-low-voltage AUC family, which is optimized for 0.8-V to 2.7-V VCC operation.

Key Features

• Low On-State Resistance: The switch features a low on-state resistance (ron), which typically stands at 0.5 Ω at a VCC of 2.3 V. This ensures minimal signal distortion and power loss across the switch.
• High Speed: With a switching speed (tON/OFF) of less than 0.5 ns at 2.3 V, it is suitable for high-frequency signal switching, making it ideal for applications such as sample-and-hold circuits.
• Single Supply Operation: The device is designed for single supply operation, which simplifies design and power management in portable and battery-powered applications.
• Low Power Consumption: The SN74AUC1G66DBVR is characterized by a low ICC of less than 1 µA, which is crucial for power-sensitive designs.
• Control Input Voltage Level Translation: The control input (C) can be driven by a VCC level that is different from the switch I/O voltage, allowing for voltage level translation across the switch.
• Break-Before-Make Switching: This feature prevents momentary shorting when switching between two signals, offering a safer and more reliable operation.
• ESD Protection: The device includes on-chip ESD protection circuits to prevent damage from electrostatic discharges during handling and operation.

Applications

The versatility of the SN74AUC1G66DBVR makes it suitable for a wide range of applications, including:

• Mobile Phones
• PDAs and Portable Devices
• Signal Gating
• Analog and Digital Multiplexing
• Sample-and-Hold Circuits
• Audio and Video Switching

Package Information

The device is available in a small-outline transistor (SOT-23) package, referenced as DBV, which is ideal for space-constrained applications. The package is RoHS compliant and designed for surface-mount technology (SMT) assembly.
