TS3A4742DGKR Description

The TS3A4742DGKR is a high-performance analog switch designed by Texas Instruments, offering exceptional electrical characteristics and reliability. This device features a maximum on-state resistance (Ron) of 900 mOhm, ensuring minimal power loss and high efficiency in signal routing applications. The switch operates within a supply voltage range of 1.6V to 3.6V, making it suitable for a variety of low-power and portable electronic systems. With a leakage current (IS(off)) of only 2nA, the TS3A4742DGKR ensures minimal power consumption when the switch is off, contributing to extended battery life in battery-operated devices.

The TS3A4742DGKR also boasts a channel-to-channel matching (ΔRon) of 30 mOhm, which is crucial for maintaining signal integrity in multi-channel applications. The switch's channel capacitance (CS(off), CD(off)) is rated at 23pF and 20pF, respectively, ensuring fast switching times and minimal signal distortion. The switch time (Ton, Toff) is maximized at 14ns and 9ns, respectively, providing rapid signal switching capabilities. The -3dB bandwidth of 125MHz allows for high-frequency signal transmission without significant attenuation.

The TS3A4742DGKR is packaged in an 8-VSSOP surface-mount package, making it ideal for compact and space-constrained designs. The device is REACH unaffected and RoHS3 compliant, ensuring it meets the highest environmental and regulatory standards. The moisture sensitivity level (MSL) is rated at 1 (unlimited), making it highly resistant to moisture-related issues during manufacturing processes.
