ELECTRICAL SPECIFICATIONS
This section describes the electrical and timing specifications of the
MC68HC05SB7.
18.1 MAXIMUM RATINGS
NOTE
Maximum ratings are the extreme limits the device can be exposed to without
causing permanent damage to the chip. The device is not intended to operate at
these conditions.
The MCU contains circuitry that protect the inputs against damage from high
static voltages; however, do not apply voltages higher than those shown in the
table below. Keep V and V
within the range from V ≤ (V or V
) ≤ V .
