SPT9691

GENERAL INFORMATION

The SPT9691 is an ultrahigh-speed dual voltage compara-

tor. It offers tight absolute characteristics. The device has

differential analog inputs and complementary logic outputs

compatible with ECL systems. The output stage is adequate

for driving terminated 50 ohm transmission lines.

The SPT9691 has a complementary latch enable control for

each comparator. Both should be driven by standard ECL

logic levels.

A common mode voltage range of -4 V to +8 V is achieved by

a proprietary JFET input design which requires a separate

negative power supply (AVEE).

The dual comparators have separate AVCC, AVEE, DVEE, and

grounds for each comparator to achieve high crosstalk rejec-

tion. Single channel operation can be accomplished by float-

ing all pins (including the ground and supply pins) of the

unused comparator. Power dissipation during single channel

operation is 50% of the dissipation during dual channel

operation.
