IDT73720/A 16-BIT TRI-PORT BUS EXCHANGER

COMMERCIAL TEMPERATURE RANGE

11.5

6

NOTES:

°C ambient.

3. Not more than one output should be shorted at a time. Duration of the short circuit test should not exceed one second.

5. This parameter is not directly testable, but is derived for use in Total Power Supply Calculations.

All currents are in milliamps and all frequencies are in megaherz.
