MT90840
Preliminary Information
2-276
Timing is over recommended temperature & power supply voltages.
Typical figures are at 25
°
C and are for design aid only: not guaranteed and not subject to production testing.
* High Impedance is measured by pulling to the appropriate rail with R
L
, with timing corrected to cancel time taken to discharge C
L
.
** Individual writes to Connection Memories will have Register Acknowledgment Delay. Burst writes to Connection Memories will have Read
Connection Memory Acknowledgment Delay.
AC Electrical Characteristics
- Motorola Multiplexed Bus Mode
Voltages are with respect to ground (V
SS
) unless otherwise stated.
