The SPT9689 is a Subnanosecond monolithic dual com-parator. The propagation delay variation is less than100 ps from 5 to 50 mV input overdrive voltage. The inputslew rate is 10 V/ns. The device utilizes a high precisiondifferential input stage with a common-mode range of2.5 V to +4.0 V.ECL-compatible complementary digital outputs are ca-pable of driving 50 Ω terminated transmission lines andproviding 30 mA output drive. The SPT9689 is pin compat-ible with the SPT9687. It is available in 20-lead PLCC and20-contact LCC packages over the industrial temperaturerange. The SPT9689 is also available in die form.
