RS0204YTQF14

This 4-bit non-inverting translator is a bidirectional voltagelevel translator and can be used to establish digital switching compatibility between mixed-voltage systems. It uses two separate configurable power-supply rails, with the A ports supporting operating voltages from 1.2V to 3.6V while it tracks the VCCA supply, and the B ports supporting operating voltages from 1.65V to 5.5V while it tracks the VCCB supply. This allows the support of both lower and higher logic signal levels while providing bidirectional translation capabilities between any of the 1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5V voltage nodes. VCCA must not exceed VCCB. When the output-enable (OE) input is low, all outputs are placed in the high-impedance state, which significantly reduces the power-supply quiescent current consumption. OE has an internal pull-down current source, as long as VCCA is powered. 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 RS0204 is available in Green QFN3.5x3.5-14L, QFN1.7x2-12L and TSSOP-14 packages. It operates over an ambient temperature range of -40°C to +85°C.
