Concerning Differences of the Mask Version and the Flash Version
1) Although the electrical specifications are the same for the mask and flash versions, differences may arise in the
actual values for threshold level of the input ports, output current of the output ports, input sensitivity, etc.
Variations may also be found from lot to lot. It must therefore be kept in mind that if finished products are designed
using the actual values of the samples, these variations may prevent the finished products from operating.
2) The undesirable radiation level is not listed among the specifications. Since differences may arise between the
mask and flash versions, this must be kept in mind when designing the finished products.
