NLAS8252数据手册集成电路（IC）的模拟开关-特殊用途规格书PDF

描述 Description

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 RON: 4 Ω (max) at 4.2 V VCC, 5 Ω (typ) at a 3.3 V VCC. It also features low CON, less than 30 pF (max) across the supply voltage range. This performance makes it ideal for USB full speed applications that require both low RON and CON for effective signal transmission. The NLAS8252 is capable of accepting control input signals down to 1.4 V, over a range of VCC 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.
