The NLAS8252 is a DP3T switch for combined UART and USB 2.0 full speed data applications. It allows portable systems to use a single external port to transmit and receive signals to and from three separate locations within the portable system. It is comprised of two switches, each with a single common I/O that alternates between 3 terminals. They are operated together to allow three data sources, such as a USB or UART transceiver, to pass differential data through a shared USB connector port. The NLAS8252 features low R: 4 O (max) at 4.2 V V, 5 O (typ) at a 3.3 V V. It also features low C, less than 30 pF (max) across the supply voltage range. This performance makes it ideal for USB full speed applications that require both low R and C for effective signal transmission. The NLAS8252 is capable of accepting control input signals down to 1.4 V, over a range of V supply voltages with minimal leakage current. The NLAS8252 is offered in a lead-free, 12 pin, 1.7 x 2.0 x 0.5 mm, UQFN package.
- RON: 4 Ohms Max @ VCC = 4.2 V
- CON: < 20 pF @ VCC = 3.3 V
- OVT Protection up to 5.25 V on Common Pins
