It uses a high speed monolithic process to provide high dc accuracy without sacrificing input voltage range. The AD1317 guarantees a 2.8 ns maximum propagation delay. On-chip connection of the common input eliminates the contributions of a second bonding pad and package pin to the input capacitance, resulting in a maximum input capacitance of 2 pF. The dispersion, or variation in propagation delay with input overdrive levels and slew rates, is typically 350 ps for 5 V signals and 200 ps for 1 V inputs. The AD1317 employs a high precision differential input stage with a common-mode range of 9 V. Its complementary digital outputs are ECL compatible. The output stage is capable of driving a 50 line terminated to –2 V. The AD1317 also provides a latch function, allowing operation in a sample-hold mode. The latch inputs can also be used to generate hysteresis. The comparator input can be switched into a high impedance state through the inhibit mode feature, electrically removing the comparator from th……
