The MC1650 and the MC1651 are very high speed comparators utilizing differential amplifier inputs to sense analog signals above or below a reference level. An output latch provides a unique sample-hold feature. The MC1650 provides high impedance Darlington inputs, while the MC1651 is a lower impedance option, with higher input slew rate and higher speed capability.

The clock inputs (C

a

and Cb) operate from MECL III or MECL 10,000 digital

levels. When C

a

is at a logic high level, Q0 will be at a logic high level provided

that V1 u V2 (V1 is more positive than V2). Q

0 is the logic complement of Q0. When the clock input goes to a low logic level, the outputs are latched in their present state.

Assessment of the performance differences between the MC1650 and the

MC1651 may be based upon the relative behaviors shown in Figures 4 and 7.

• PD= 330 mW typ/pkg (No Load)

• tpd= 3.5 ns typ (MC1650)

= 3.0 ns typ (MC1651)

• Input Slew Rate = 350 V/µs (MC1650) = 500 V/µs (MC1651)

• Differential Input Voltage: 5.0 V (–30°C to +85° C)

• Common Mode Range:

–3.0 V to +2.5 V (–30°C to +85°C) (MC1651) –2.5 V to +3.0 V (–30°C to +85°C) (MC1650)

• Resolution: p 20 mV (–30°C to +85°C)

• Drives 50 Ω lines

Number at end of terminal denotes pin number for L package (Case 620).

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–ohm resistor to –2.0 volts. Test procedures are shown for only one gate. The other gates are tested in the same manner.
