2. When the delay time is short, M51951, M51952, M51955 and M51956 are available. These ICs have a
3. If the M5195xx and the logic circuit share a common power source, type A (built-in load type) can be used
4. The logic circuit preferably should not have a pull-down resistor, but if one is present, add load resistor R
5. When the reset terminal in the logic circuit is of the low reset type, M51951, M51953, M51955 and M51957
6. When a negative supply voltage is used, the supply voltage side of M5195xx and the GND side are
When the voltage is anything except 4.25 V, M51955, M51956, M51957 and M51958 are used.
