Window 4ns High-Speed Comparator
Features
The EL5287 comparator is designed
for operation in single supply and dual
supply applications with 5V to 12V
• 4ns typ. propagation delay
• 5V to 12V input supply
• +2.7V to +5V output supply
• True-to-ground input
between V + and V -. For single supplies, the inputs can
operate from 0.1V below ground for use in ground sensing
applications.

• Rail-to-rail outputs
The output side of the comparators can be supplied from a
single supply of 2.7V to 5V. The rail-to-rail output swing
enables direct connection of the comparator to both CMOS
and TTL logic circuits.
• Separate analog and digital supplies
• Active low latch
• Single available (EL5185)
• Dual available (EL5285)
• Quad available (EL5485 & EL5486)
The latch input of the EL5287 can be used to hold the
comparator output value by applying a low logic level to the
pin.
• Pin-compatible 6ns family available (EL5x81, EL5283 &
EL5482)
The EL5287 is a window comparator. A single input is
compared with a high reference and a low. When the output
goes beyond one of these reference signals, the relevant
output goes low.
Applications
• Threshold detection
• High speed sampling circuits
• High speed triggers
• Line receivers
The EL5287 is available in the 10-pin MSOP package and is
specified for operation over the full -40°C to +85°C
temperature range. Also available are a single (EL5185) and
quad versions (EL5485 and EL5486).
