The TS3A4742DGKR is a state-of-the-art analog switch from Texas Instruments, designed to deliver high performance in a compact package. This device is particularly suitable for applications that require a low on-state resistance, low crosstalk, and low off-state leakage current. The switch is a part of the family of 1-Ohm SPDT (Single Pole Double Throw) switches that are bidirectional and designed to handle both analog and digital signals.

Key Features

• Low On-State Resistance: The device boasts an exceptionally low on-state resistance of typically 1 ohm, which ensures minimal signal distortion and power loss when the switch is in the on position.
• Wide Operating Voltage Range: It operates over a broad voltage range from 2.3V to 3.6V, making it versatile for various low-voltage applications.
• Single Supply Operation: The TS3A4742DGKR is designed for single supply operation, which simplifies power supply design and reduces component count.
• Break-Before-Make Switching: This feature prevents signal overlap when switching between channels, thus eliminating potential shorting of signals.
• Low Power Consumption: With its low power consumption, the switch is ideal for battery-powered devices, ensuring longer battery life and efficiency.
• High ESD Protection: The device offers excellent electrostatic discharge (ESD) protection, safeguarding the switch from inadvertent static discharges.
