The MC12018 is a dual modulus prescaler which divides by 128 and 129.
An internal regulator is provided to allow this device to be used over a wide
range of power supply voltages. The devices may be operated by applying a
supply voltage of 5.0 Vdc
±
10% at Pin 7, or by applying an unregulated
voltage source from 5.5 Vdc to 9.5 Vdc to Pin 8.
520 MHz Toggle Frequency
Low–Power 8.0 mA Typical
Control Input Is Compatible With Standard CMOS and TTL
Supply Voltage 4.5 V to 9.5 V
On–Chip 10 k
Resistor from Positive Edge to Ground

1. Vreg at Pin 7 is not guaranteed to be between 4.5 and
5.5 V when VCC is being applied to Pin 8
2. Pin 7 is not to be used as a source of regulated output
