DESCRIPTION
The UTC UVXS0102 is a two-bit non-inverting bidirectional
voltage-level translator and can be used to establish digital
switching compatibility between mixed-voltage systems.
The UTC UVXS0102 separates A ports with B ports, and both
ports are configurable power-supply rails, with the A ports
supporting operating voltages from 1.65V to 3.6V, and the B ports
supporting operating voltages from 2.3V to 5.5V. This allows the
support of both lower and higher logic signal levels while providing
bidirectional translation capabilities between any of the 1.8V, 2.5V,
3.3V, and 5V voltage nodes.
All I/Os of the UTC UVXS0102 are placed in the
high-impedance state when the output-enable (OE) input is low,
which significantly reduces the power-supply quiescent current
consumption. So, to ensure the high-impedance state during power
up or power down, OE should be tied to GND through a pull-down
resistor; the minimum value of the resistor is determined by the
current-sourcing capability of the driver.
FEATURES
* Maximum Data Rates
24 Mbps (Push Pull)
2 Mbps (Open Drain)
* 1.65V~3.6V on A ports and 2.3V~5.5V on B ports (VCCA≤VCCB
* No Direction-Control Signal Needed
)
* VCC Isolation Feature: If either VCC input is at GND, both ports are
in the High-Impedance state
* No Power-Supply Sequencing Required: Either VCCA or VCCB can
be ramped first
* Ioff Supports Partial-Power-Down Mode Operation
