The MB86933H is the default owner of the bus.
PACKAGE THERMAL CHARACTERISTICS
DC SPECIFICATIONS3 VCC = 5V + 5%
*1 Note: Use ICC (typ) values to calculate maximum case and ambient temperature allowed. Note that maximum junction temperature of die is 1255C. For example, Allowed ambient temp = 1255C.- (ICC) (5.25V) jJA
AC CHARACTERISTICS1,2,4 VCC = 5V + 5%
AC CHARACTERISTICS1,2,4 VCC = 5V + 5%
1. Parameters are valid over specified temperature range and supply voltage range unless otherwise noted.
2. All voltage measurements are referenced to ground. All time measurements are referenced at input and output levels of 1.5V. For testing, all inputs swing between 0.4V and 2.4V (Except XTAL1 which swings from 0.4V to 3.0V). Input rise and fall times are 2ns or less.
3. Not more than one output may be shorted at a time for a maximum duration of one second.
4. Timing specifications apply to frequency of operation listed at top of column.
5. All output timings are based on a 50pF load.
7. These specs will be improved in the future.
8. Data bus output driver control is same as for RD/-WR so timing is similar.
Interrupt Signal, Interrupt Input Width
1. In HIGH Level or RISING-EDGE trigger mode, if this width is satisfied, the interrupt request FLIP-FLOP is set.
2. In LOW Level or FALLING-EDGE trigger mode, if this width is satisfied, the interrupt request FLIP-FLOP is set.
