Key Specifications
Product Description The UM3602 is a dual-supply, dual-bit non-inverting bus transceiver that is optimized to operate with VCCA and VCCB set at 1.65V to 5.5V. The A port is designed to track VCCA which accepts any supply voltage from 1.65V to 5.5V. The B port is designed to track VCCB which accepts any supply voltage from 1.65V to 5.5 V. This allows for universal low-voltage bidirectional translation between any of the 1.8V, 2.5V, 3.3V, and 5.5V voltage nodes. The UM3602 is designed for asynchronous communication between two data buses. The logic levels of the direction-control (DIR) input activate either the B-port output and the A-port outputs. The device transmits data from the A bus to the B bus when the B-port outputs are activated, and from the B bus to the A bus when the A-port outputs are activated. The input circuitry on both A and B ports is always active and must have a logic HIGH or LOW level applied to prevent excess ICC and ICCZ. In the design of the UM3602, the control pin (DIR) is supplied by VCCA. The UM3602V8 is available in VSSOP8 package. Features
- Control Inputs VIH/VIL Levels Are Referenced to VCCA Voltage - VCC Isolation Feature – If Either VCC Input Is at GND, All Are in the High-Impedance - Fully Configurable Dual-Rail Design Allows Each Port to Operate Over the Full 1.65V to 5.5V Power-Supply Range - Low Power Consumption, 10-μA Max ICC - ±24-mA Output Drive at 3.3 V - Available in VSSOP8 Package - Max Data Rates:
150 Mbps(VCCA<3.3 V or VCCB<3.3 V)
220 Mbps(VCCA≥3.3 V and VCCB≥3.3 V)
