EL5481C/EL5482C
Quad 8ns High-Speed Comparators
Features
General Description
• 8ns Typ. Propagation Delay
• 5V to 12V Input Supply
• +2.7V to +5V Output Supply
• True-to-ground Input
The EL5481C and EL5482C comparators are designed for operation
in single supply and dual supply applications with 5V to 12V between
V + and V -. For single supplies, the inputs can operate from 0.1V
S
S
below ground for use in ground sensing applications.
• Rail-to-rail Outputs
• Active Low Latch
• Single (EL5181C) Available
• Dual (EL5281C) Available
• Window Available (EL5283C)
The output side of the comparators can be supplied from a single sup-
ply of 2.7V to 5V. The rail-to-rail output swing enables direct
connection of the comparator to both CMOS and TTL logic circuits.
The latch input of the EL5482C can be used to hold the comparator
output value by applying a low logic level to the pin.
• Pin-compatible 4ns Family
Available (EL5185C, EL5285C,
EL5287C, EL5485C & EL5486C)
The EL5481C is available in the 16-pin SO (0.150") package and the
EL5482C 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 (EL5181C), a dual (EL5281C), and a window comparator
(EL5283C).
