High-Speed Comparator Cross Reference

Other Parts Discussed in Thread: TLC354, TLV2354, TLC374, LMV339, TLC339

I am looking for a high-speed comparator from TI that is a cross or at least a comparable part to the MAX944 3/5V high-speed RRIO comparator.

The key requirements are response time 120ns or less, RRIO and is in a quad-14pin or 16 pin dip package.

Please let me know if TI has something close...

Thanks

Hi Terry,

While I don't think we have an exact fit our fastest quads have a max spec of 200ns and are the TLV2354, LMV339, TLC354 and TLC374. For RRIO, the widest common mode looks to be on the LMV339, but the conditions of your design always play a role.

Best,

Gina

Terry;

I've used the TLC339 quad CMOS comparator frequently and found it quite satisfactory. It is rated at 3us response time but with more overdrive, it gets down to about 1us.

Nice photo, Gina!
