Frequently Asked Questions
What types of supplies can the ald2302 comparators operate with?
They support both single (+5V) and dual supply (±5V) operation, with a low operating voltage range of 4V to 12V.
Can I use this comparator for wired-OR connections?
Yes, the outputs can be used in wired-OR connection (up to three units for TTL levels) or push-pull configuration. This eliminates the need for pull-up resistors.
What is the maximum output current capability of one unit?
Each comparator has a high output sinking and sourcing current capacity of 60mA, offering application flexibility.
Which package options are available and what is the temperature range for each?
Packages include CERDIP, SOIC, and small outline plastic dip. The DA package supports an industrial temperature range of -55°C to +125°C.
