FEATURES
DESCRIPTION
TheLT®1015isadualhighspeedcomparatorintendedfor
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.
■
Response Time: 10ns
■
Setup Time for Latch: 2ns
■
Operates on Single 5V Supply
■
Dual Function in 8-Pin Package
■
No Input Slew Rate Requirement
Latch Function Included on Chip

■
True Differential UInputs
APPLICATIONS
■
High Speed Differential Line Receiver
Pulse Height/Width Discriminator
Timing and Delay Generators
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.
