Description
AW39214 is a 4-bit high-performance voltage-level translator without direction control signal, that enables bidirectional voltage level translation. It features two 4-bit input-output ports (An and Bn), one output enable input (OE) and two supply pins (VCCA and VCCB). VCCA can be supplied with any voltage between 1.2V and 3.6V. VCCB can be supplied with any voltage between 1.65V and 5.5V. The range of supply voltages makes the device suitable for translating between any of the low voltage nodes (1.2V, 1.5V, 1.8V, 2.5V, 3.3V and
5.0V).
The AW39214 is designed so that the OE input circuit is supplied by VCCA. When the output-enable (OE) input is low, all outputs are placed in the high-impedance state. To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.
