Dual Modulus Prescaler
These devices are two–modulus prescalers which will divide by 5 and 6, 8 and 9, and 10 and 11, respectively. A MECL–to–MTTL translator is provided to interface directly with the MC12014 Counter Control Logic. In addition, there is a buffered clock input and MECL bias voltage source. MC12009 480 MHz ( 5/6), MC12011 550 MHz ( 8/9), MC12013 550 MHz ( 10/11) MECL to MTTL Translator on Chip

* When using a 5.0 V supply, apply 5.0 V to Pin 1 (VCCO ), Pin 6 (MTTL V CC ), Pin 16 (V CC ), and ground Pin 8 (V EE ). When using –5.2 V supply, ground Pin 1 (V CCO ), Pin 6 (MTTL V CC ), and Pin 16 (V CC ) and apply –5.2 V to Pin 8 (V EE ). If the translator is not required, Pin 6 may be left open to conserve dc power drain.
