SECTION 11
ELECTRICAL CHARACTERISTICS
The AC characteristics presented consist of output delays, input setup and hold times,
and signal skew times. All signals are specified relative to an appropriate edge of the
clock(s) and possibly to one or more other signals.

MC68838 USER'S MANUAL
This device contains protective
Unit
circuitry against damage due to
high static voltages or electrical
V
fields; however, it is advised that
V
normal precautions be taken to
avoid application of any voltages
V
higher than maximum-rated
voltages to this high-impedance
mA
circuit. Reliability of operation is
mA
enhanced if unused inputs are
tied to an appropriate logic
°C
voltage level (e.g., either GND or
V CC ).
