GENERAL DESCRIPTION

The SPT9691 is a high-speed, wide common mode voltage, JFET input, dual comparator. It is designed for applications that measure critical timing parameters in which wide common mode input voltages of -4.0 to +8.0 V are required. Propagation delays are constant for overdrives greater than 200 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 compatible with ECL systems. Each comparator has a complementary latch enable control that can be driven by standard ECL logic.
