Manufacturer Part Number
SPT9689BCU
Description
DUAL ULTRAFAST VOLTAGE COMPARATOR
Manufacturer
CADEKA [Cadeka Microcircuits LLC.]
Datasheet
FEATURES
• 650 ps propagation delay
• 100 ps propagation delay variation
• 70 dB CMRR
• Low feedthrough and crosstalk
• Differential latch control
• ECL compatible
GENERAL DESCRIPTION
The SPT9689 is a Sub nanosecond monolithic dual com-
parator. The propagation delay variation is less than
100 ps from 5 to 50 mV input overdrive voltage. The input
slew rate is 10 V/ns. The device utilizes a high precision
differential input stage with a common-mode range of
–2.5 V to +4.0 V.

APPLICATIONS
• Automated test equipment
• High-speed instrumentation
• Window comparators
• High-speed timing
• Line receivers
• High-speed triggers
• Threshold detection
• Peak detection
ECL-compatible complementary digital outputs are ca-
pable of driving 50
providing 30 mA output drive. The SPT9689 is pin compat-
ible with the SPT9687. It is available in 20-lead PLCC and
20-contact LCC packages over the industrial temperature
range. The SPT9689 is also available in die form.
