MAX3345E Datasheet | Maxim Integrated

Description The MAX3344E/MAX3345E USB transceivers convert logic-level signals to USB signals, and USB signals to logic-level signals. An internal 1.5kΩ USB pullup resistor supports full-speed (12Mbps) USB operation. The MAX3344E/MAX3345E provide built-in ±15k V ESD-protection circuitry on the USB I/O pins, D+ and D-, and VCC. The MAX3344E/MAX3345E operate with logic supply voltages as low as 1.65V, ensuring patibility with low-voltage ASICs. The suspend mode lowers supply current to less than 40µA. An enumerate function allows devices to logically disconnect while plugged in. The MAX3344E/MAX3345E are fully pliant with USB specification 1.1, and full-speed operation under USB specification 2.0. The MAX3344E/MAX3345E have a USB detect that monitors the USB bus for insertion and signals this event. The MAX3344E USB_DET threshold is between 3.6V (min) and 4V (max), while the MAX3345E USB_DET threshold is between 1V (min) and 2.8V (max). The MAX3344E/MAX3345E are available in the miniature 4 ✕ 4 UCSP™, as well as the small 16-pin TSSOP, and are specified over the extended temperature range, -40°C to +85°C. - - - - - - Features ±15k V ESD Protection On D+ and Dply with USB Specification 1.1 (Full Speed 2.0) Separate VP and VM Inputs/Outputs VL Down to 1.65V Allows Connection with Low Voltage ASICs Enumerate Input- Allows USB Connection through Software USB Detect Function 3.6V (min) to 4V (max)- MAX3344E 1V (min) to 2.8V (max)- MAX3345E Allow Single-Ended or Differential Logic I/O Internal Linear Regulator Allows Direct Powering from the USB Internal Pullup Resistor for Full-Speed Operation Three-State Outputs No Power-Supply Sequencing Required Driver Active in Suspend Mode Available in Miniature Chip-Scale Package MAX3344E/MAX3345E - - - - - - - Ordering Information PART MAX3344EEUE MAX3344EEBE-T MAX3345EEUE MAX3345EEBE-T TEMP RANGE -40°C to +85°C -40°C to +85°C -40°C to +85°C -40°C to +85°C PIN-PACKAGE 16 TSSOP 4 x 4 UCSP 16 TSSOP 4 x 4 UCSP Applications Cell Phones...
