General Description

The USB1T20 is a generic USB 2.0 compliant transceiver. Using a single voltage supply, the USB1T20 provides an ideal USB interface solution for any electronic device able to supply 3.0V to 3.6V. It is designed to allow 5.0V or 3.3V programmable and standard logic to interface with the physical layer of the Universal Serial Bus. It is capable of transmitting and receiving serial data at both full speed (12Mbit/s) and low speed (1.5Mbit/s) data rates.

Packaged in industry standard TSSOP and Fairchild’s ultra-small 2.5mm x 2.5mm MLP package, the USB1T20 is ideal for ultra-portable electronics and other space constrained applications.
