Key Specifications
Product Description The UM3601 is a dual-supply, single-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. VCCA accepts any supply voltage from 1.65V to 5.5V. The B port is designed to track VCCB. VCCB 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 UM3601 is designed for asynchronous communication between two data buses. The logic levels of the direction-control (DIR) input activate either the B-port output or the A-port output. 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 UM3601, the control pin (DIR) is supplied by VCCA. The UM3601S is available in SOT23-6 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 - Latch-Up Performance Exceeds 100 mA - ESD Protection Exceeds ±4kV Human-Body Model - Available in SOT23-6 Package - Max Data Rates:
220 Mbps(3.3V to 5.5V Translation)
150 Mbps(3.3V to 1.8V Translation)
