Dual Modulus Prescaler
Legacy Device: Motorola 12509, 12511, 12513
These devices are two–modulus prescalers which will divide by
5 and 6, 8 and 9, respectively. A MECL–to–MTTL translator is
provided to interface directly with the Motorola MC12014
Counter Control Logic. In addition, there is a buffered clock input
and MECL bias voltage source.
• ML12509 480 MHz (÷5/6), ML12511 550 MHz (÷8/9),
ML12513 550 MHz (÷10/11)
• MECL to MTTL Translator on Chip
• MECL and MTTL Enable Inputs
• 5.0 or –5.2 V Operation*
• Buffered Clock Input — Series Input RC Typ, 20 Ω and 4.0 pF
• VBB Reference Voltage
• 310 mW (Typ)
* When using a 5.0 V supply, apply 5.0 V to Pin 1 (VCCO),
Pin 6 (MTTL VCC), Pin 16 (VCC), and ground Pin 8
(VEE). When using –5.2 V supply, ground Pin 1 (VCCO),
Pin 6 (MTTL VCC), and Pin 16 (VCC) and apply –5.2 V to
Pin 8 (VEE). If the translator is not required, Pin 6 may be
left open to conserve DC power drain.

NOTES: 1. Test outputs of the device must be tested by sequencing through the truth table. All input, power supply and
ground voltages must be maintained between tests. The clock input is the waveform shown.
2. In addition to meeting the output levels specified, the device must divide by 5 or 8 during this test. The clock
input is the waveform shown.
3. In addition to meeting the output levels specified, the device must divide by 6 or 9 during this test. The clock
input is the waveform shown.

Each MECL 10,000 series circuit has been designed to meet the dc specifications shown in the test table, after thermal equilibrium has been
established. The circuit is in a test socket or mounted on a printed circuit board and transverse air flow greater than 500 linear fpm is maintained.
Outputs are terminated through a 50 Ω resistor to –2.0 V. Test procedures are shown for only one gate. The other gates are tested in the same
manner.
