Motorola MC12018D, MC12018P Datasheet
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 kΩ Resistor from Positive Edge to Ground
