Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor's system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild_questions@onsemi.com.

USB1T20 -- Universal Serial Bus Transceiver Features Description Complies with Universal Serial Bus Specification 2.0 for FS/LS Applications Utilizes Digital Inputs and Outputs to Transmit and Receive USB Cable Data Supports 12Mbit/s Full Speed (FS) and 1.5Mbit/s Low Speed (LS) Serial Data Transmission Supports Single-ended and Differential Data Interface as Function of MODE 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 3.0 V to 3.6 V. It is designed to allow 5.0 V or 3.3 V programmable and standard logic to interface with the physical layer of the Universal Serial Bus (USB). It is capable of transmitting and receiving serial data at both full speed (12Mbit/s) and low speed (1.5Mbit/s) data rates. Single 3.3 V Supply ESD Performance: Human Body Model - 9.5 kV on D-, D+ Pins Only - 4.0 kV on All Other Pins Packaged in industry-standard TSSOP package. The USB1T20 is ideal for mobile electronics and other space-constrained applications.
