SWITCHING CHARACTERISTICS over COMMERCIAL and INDUSTRIAL operating ranges
at 25 MHz
V
V
Notes:
1. Float condition occurs when maximum output current becomes less than I
2. These inputs are allowed to be asynchronous to CLK2. The setup and hold specifications are given for testing purposes, to
3. Rise and Fall times are not tested. They are guaranteed by design characterization.
4. Only during FLT assertion.
5. On Am386SXLV only.
