Quad 8ns High-Speed Comparators
Features
The EL5481 and EL5482 comparators
are designed for operation in single
supply and dual supply applications
• 8ns 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 (EL5181) Available
• Dual (EL5281) Available
• Window Available (EL5283)
The latch input of the EL5482 can be used to hold the
comparator output value by applying a low logic level to the
pin.
• Pin-compatible 4ns Family Available (EL5185, EL5285,
EL5287, EL5485 & EL5486)
The EL5481 is available in the 16-pin SO (0.150") package
and the EL5482 in the 24-pin QSOP package. All are
specified for operation over the full -40°C to +85°C
temperature range. Also available are a single (EL5181), a
dual (EL5281), and a window comparator (EL5283).
Applications
• Threshold Detection
• High Speed Sampling Circuits
