EL5185C - Preliminary
4ns High-Speed Comparator
Features
General Description
• 4ns typ. propagation delay
• 5V to 12V input supply
• +2.7V to +5V output supply
• True-to-ground input
The EL5185C 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 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.
• Active low latch
• Dual available (EL5285C)
• Window comparator (EL5287C)
• Quad available (EL5485C &
EL5486C)
• Pin-compatible 6ns family
available (EL5x81C, EL5283C &
EL5482C)
The latch input of the EL5185C can be used to hold the comparator
output value by applying a low logic level to the pin.
The EL5185C is available in the 8-pin SO package and is specified for
operation over the -40°C to +85°C temperature range. Also available
are dual (EL5285C), window comparator (EL5287C), and quad
(EL5485C and EL5486C) versions.
