The Pericom Semiconductor product line of Diodes Incorporated has announced the release of the industry’s smallest USB2.0 signal multiplexer, which is ideal for use in portable and space-constrained designs.
The PI3USB102J is a bi-directional 2-to-1 signal multiplexer switch with a single differential channel. It causes little attenuation of the high-speed signals it carries, and low bit-to-bit skew. Operating at a very low current of 30nA, it operates over a wide temperature range – a useful feature in thin portable products which have no fan for forced-air cooling.
The device complies with the USB2.0 standard in its Low-Speed, Full-Speed and Hi-Speed versions. It is supplied in a ten-lead QFN package with a 1.2mm x 1.4mm footprint, and a height of just 0.35mm.
Featuring integrated over-voltage protection, the PI3USB102J can tolerate a short to the power-supply bus at the micro-USB or USB Type-CTM connector.
