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 mon input eliminates the contributions of a second bonding pad and package pin to the input capacitance, resulting in a maximum input capacitance of 2 p F. 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 mon-mode range of 9 V. Its plementary digital outputs are ECL patible. The output stage is capable of driving a 50 Ω 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 parator input can be switched into a high impedance state through the inhibit mode feature , electrically removing the parator from the circuit. The bias current in inhibit mode is typically 50 p A. The AD1317 is available in a small 16-lead, hermetically sealed “gull-wing” surface mount package and operates over the mercial temperature range, 0°C to +70°C. REV.
