SN65240P Datasheet | Texas Instruments

Features - Design to protect submicron 3-V or 5-V circuits from noise transients - Port ESD protection capability exceeds: - 15-k V human body model - 2-k V machine model - Available in a WCSP chip-scale package - Stand-off voltage: 6 V (minimum) - Low current leakage: 1-µA maximum at 6 V - Low capacitance: 35-p F (typical) 2 Applications - USB full-speed host, HUB, or peripheral - Ports USB Transceiver 27 D+ 15 k GND SN65220 or ½ SNx5240 15 k D- Simplified Schematic 3 Description The SN65220 device is a dual, and the SN65240 and SN75240 devices are quadruple, unidirectional transient voltage suppressors (TVS). These devices provide electrical noise transient protection to Universal Serial Bus (USB) low and full-speed ports. The input capacitance of 35 p F makes it unsuitable for high-speed USB 2.0 applications. Any cabled I/O can be subjected to electrical noise transients from various sources. These noise transients can cause damage to the USB transceiver or the USB ASIC if they are of sufficient magnitude and duration. The SN65220, SN65240, and SN75240 devices ESD performance is measured at the system level, according to IEC61000-4-2; system design, however, impacts the results of these tests. To acplish a high pliance level requires careful board design and layout techniques.
