EL5281C
Dual 8ns High-Speed Comparator
Features
General Description
• 8ns Typ. Propagation Delay
• 5V to 12V Input Supply
• +2.7V to +5V Output Supply
• True-to-ground Input
The EL5281C comparator is 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 below ground for
use in ground-sensing applications.

• Rail-to-rail Outputs
• Active Low Latch
• Single Available (EL5181C)
The output side of the comparator 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.
• Quad Available (EL5481C &
EL5482C)
• Pin-compatible 4ns Family
Available (EL5x85C, EL5287C &
EL5486C)
The latch input of the EL5281C can be used to hold the comparator
output value by applying a low logic level to the pin. The EL5281C
features two separate comparators.
The EL5281C 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 (EL5181C) and quad versions (EL5481C and
EL5482C).
Applications
• Threshold Detection
• High Speed Sampling Circuits
• High Speed Triggers
• Line Receivers
• PWM Circuits
• High Speed V/F Converters
