PRODUCT DESCRIPTION
The AD1317 is an ultrahigh speed window comparator with a
latch. 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 contri-
butions 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
vides 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 the circuit. The bias current in inhibit mode is
typically 50 pA.
The AD1317 is available in a small 16-lead, hermetically sealed
“gull-wing” surface mount package and operates over the com-
mercial temperature range, 0 C to +70 C.
