Dual 4ns High-Speed Comparator
Features
The EL5285 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.
• Active low latch
• Single available (EL5185)
• Window available (EL5287)
• Quad available (EL5485 & EL5486)
The latch input of the EL5285 can be used to hold the
comparator output value by applying a low logic level to the
pin. The EL5285 features two separate comparators
• Pin-compatible 8ns family available (EL5x81, EL5283 &
EL5482)
The EL5285 is available in the 14-pin SO package and is
specified for operation over the full -40°C to +85°C
temperature range. Also available are a single (EL5185),
window comparator (EL5287), and quad versions (EL5485
and EL5486).
Applications
