UM3302H/UM3302Q

2-Bit Bidirectional Voltage-Level Translator with Auto Direction

sensing and ±15kV ESD Protection

UM3302H CSP8 1.90×0.90

UM3302Q QFN8 1.40×1.20

General Description

The UM3302, a ESD protected level translator, provides the level shifting necessary to allow data

transfer in multi-voltage system. This 2-channel noninverting translator uses two separate

configurable power-supply rails. The A port is designed to track V_CCA. V_CCAaccepts any supply

voltage from 1.2V to 3.6V. The B port is designed to track V_CCB. V_CCBaccepts any supply voltage

from 1.65V to 5.5V. This allows for universal low-voltage bidirectional translation between any

of the 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V voltage nodes. Both I/O ports are auto-sensing; thus,

no direction pin is required, making it ideal for data transfer between low-voltage ASICs /PLDs

and higher voltage systems.

The UM3302 operates at a guaranteed data rate of 20Mbps over the entire specified operating

voltage range. Within specific voltage domains, higher data rates are up to 100Mbps.

When the output-enable (OE) input is low, all outputs are placed in the high-impedance state. The

UM3302 is designed so that the OE input circuit is designed to track V_CCA

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.

The UM3302H is a dual channel level translator available in 1.90mm×0.90mm CSP8 bump

package while UM3302Q is available in 1.40mm×1.20mm QFN8 package.
