Description:

The NTE7096 and NTE7097 are integrated circuits in 8–Lead DIP type packages that incorporate a new precision temperature–controlled oscillator with an internally trimmed discharge current to minimize variations in frequency. A precision duty–cycle clamp eliminates any need for an external oscillator when at, or near, a 50 duty–cycle condition. Duty–cycles greater than 50 are also possible. Special logic ensures that Vref is stabilized before the output stage is enabled. Ion–implant resistors provide tighter control of under–voltage lockout.
