Dual 8ns High-Speed Comparator
Features
The EL5281 comparator is designed
for operation in single supply and dual
supply applications with 5V to 12V
• 8ns 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 comparator 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 (EL5181)
• Quad Available (EL5481 & EL5482)
The latch input of the EL5281 can be used to hold the
comparator output value by applying a low logic level to the
pin. The EL5281 features two separate comparators.
• Pin-compatible 4ns Family Available (EL5x85, EL5287 &
EL5486)
Applications
The EL5281 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 (EL5181) and
quad versions (EL5481 and EL5482).
