GENERAL DESCRIPTION

The SPT9693 is a high-speed, wide common mode volt-

age, JFET input, dual comparator. It is designed for appli-

cations that measure critical timing parameters in which

wide common mode input voltages of –3.0 to +8.0 V are

required. Propagation delays are constant for overdrives

greater than 50 mV.

JFET inputs reduce the input bias currents to the

nanoamp level, eliminating the need for input drivers and

buffers in most applications. The device has differential

analog inputs and complementary logic outputs com-

patible with ECL systems. Each comparator has a

complementary latch enable control that can be driven by

standard ECL logic.

The SPT9693 is available in 20-contact LCC and 20-lead

PLCC packages over the commercial temperature range.

It is also available in die form.
