MECL Components Dual Modulus Prescaler
Legacy Device: Motorola 12509, 12511, 12513
These devices two-modulus prescalers which will divide respectively. MECL-to-MTTL translator provided interface directly with Motorola MC12014 Counter Control Logic. addition, there buffered clock input MECL bias voltage source. ML12509 (÷5/6), ML12511 (÷8/9), ML12513 (÷10/11) MECL MTTL Translator Chip MECL MTTL Enable Inputs -5.2 Operation* Buffered Clock Input Series Input Typ, Reference Voltage (Typ) When using supply, apply (VCCO), (MTTL VCC), (VCC), ground (VEE). When using -5.2 supply, ground (VCCO), (MTTL VCC), (VCC) apply -5.2 (VEE). translator required, left open conserve power drain.
