EL5285C - Preliminary
Dual and Window 4ns High-Speed Comparators
Features
General Description
• 4ns typ. propagation delay
• 5V to 12V input supply
• +2.7V to +5V output supply
• True-to-ground input
The EL5285C comparator is designed for operation in single supply
and dual supply applications with 5V to 12V between VS+ and VS-.
For single supplies, the inputs can operate from 0.1V below ground for
use in ground sensing applications.
• Rail-to-rail outputs
• Separate analog and digital
supplies
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.
• Active low latch
• Single available (EL5185C)
• Quad available (EL5485C &
EL5486C)
• Pin-compatible 6ns family
available (EL5x81C, EL5283C &
EL5482C)
The latch input of the EL5285C can be used to hold the comparator
output value by applying a low logic level to the pin. The EL5285C
features two separate comparators
The EL5285C 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 (EL5185C) and quad versions (EL5485C and
EL5486C.)
Applications
• Threshold detection
• High speed sampling circuits
• High speed triggers
• Line receivers
• PWM circuits
Pin Configurations
• High speed V/F converters
