USB1T11A — Universal Serial Bus Transceiver Features Description Complies with Universal Serial Bus Specification 1.1 Utilizes Digital Inputs and Outputs to Transmit and Receive USB Cable Data Supports 12Mbit/s “Full Speed” and 1.5Mbit/s “Low Speed” Serial Data Transmission Compatible with the VHDL “Serial Interface Engine” from USB Implementers' Forum Supports Single-ended Data Interface Single 3.3V Supply ESD Performance: Human Body Model The USB1T11A is a one-chip, generic USB transceiver. 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. The input and output signals of the USB1T11A conform with the “Serial Interface Engine.” Implementation of the serial interface engine allows designers to make USBcompatible devices with off-the-shelf logic to modify and update the application. >9.5kV on D-, D+ pins only >4kV on all other pins Ordering Information Operating Temperature Range Package Packing Method USB1T11AM 14-Lead, Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150-Inch Narrow Tube USB1T11AMX 14-Lead, Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150-Inch Narrow Tape and Reel Part Number -40 to +85°C USB1T11AMTC 14-Lead, Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Tube USB1T11AMTCX 14-Lead, Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Tape and Reel D- /OE SPEED VMO/FSE0 D+ VPO RCV + - VP VM Figure 1.
