NTE978

Dual Timer IC

NTE Electronics 

Note 2. Supply current when output high typically 1mA less at VCC = 5V.

Note 3. Tested at VCC = 5V and VCC = 15V.

Note 4. As reset voltage lowers, timing is inhibited and then the output goes low.

Note 5. This will determine the maximum value of RA + RB for 15V operation. The maximum total

(RA + RB) is 20MΩ.

Note 6. No protection against excessive Pin1, Pin13 current is necessary providing the package dis-

sipation rating will not be exceeded.

Note 7. Matching characteristics refer to, the difference between performance characteristics of

each timer section.
