ISOW7843: Production schedule for ISOW7842 and other variations?

Part Number: ISOW7843

Currently the ISOW7841 (3 outputs, 1 input) is the only part available through distribution. Do you have a schedule for when the other variations, such as the ISOW7842 (2 outputs, 2 inputs) or ISOW7843 (1 output, 3 inputs) will be in production and available through distribution?
