MC12019 Datasheet, PDF (1/4 Pages) Freescale Semiconductor, Inc – Dual Modulus Prescaler

Dual Modulus Prescaler
The MC12019 is a divide by 20 and 21 dual modulus prescaler. It will
divide by 20 when the modulus control input is HIGH and divide by 21 when
the modulus control input is LOW.
• 225 MHz Toggle Frequency
• Low-Power 7.5 mA Maximum at 5.5 V
• Control Input is Compatible with Standard Motorola CMOS Synthesizers
• Emitter Follower Output
