DESCRIPTION
The LT ®1015 is a dual high speed comparator intended for
line receiver and other general purpose fast comparator
functions. It has 10ns response time, true differential
inputs, TTL outputs and operates from a single 5V supply.
A unique output stage design virtually eliminates power
supply glitching during transitions. This greatly reduces
instability and crosstalk problems in multiple line applica-
tions. No minimum input slew rate is required as in
previous TTL output comparators.
The LT1015 has a true Latch pin for retaining output data.
Setup time is 2ns, allowing the comparators to capture
data much faster than the actual flowthrough response
time. 8-pin miniDIP and ceramic packages allow high
packing density.
