(2) Tested at VCC = 5 V and VCC = 15 V. (3) This will determine the maximum value of RA + RB for 15-V operation. The maximum total (RA + RB) is 20 MΩ. (4) No protection against excessive pin 1, 13 current is necessary providing the package dissipation rating will not be exceeded. (5) Matching characteristics refer to the difference between performance characteristics of each timer section.
