Quad 4ns High Speed Comparators
Features
The EL5485 and EL5486 comparators
are designed for operation in single
supply and dual supply applications
• 4ns typ. propagation delay
• 5V to 12V input supply
• +2.7V to +5V output supply
• True-to-ground input
with 5V to 12V between V + and V -. For single supplies,
S
S
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 (EL5185) available
• Dual (EL5285) available
• Window available (EL5287)
The latch input of the EL5486 can be used to hold the
comparator output value by applying a low logic level to the
pin.
• Pin-compatible 8ns family available (EL5x81, EL5283 &
EL5482)
The EL5485 is available in the 16-pin SO (0.150") package
and the EL5486 in the 24-pin QSOP package. Both are
specified for operation over the full -40°C to +85°C
temperature range. Also available are single (EL5185), dual
(EL5285), and window comparator (EL5287) versions.
Applications
• Threshold detection
• High speed sampling circuits
• High speed triggers
• Line receivers
