Product Overview
TLV3501AIDR is a very fast single comparator for timing, threshold and zero-crossing applications where tens-of-nanoseconds devices are still too slow. The 4.5-ns class propagation delay pushes layout and input overdrive into the same importance level as the IC specification itself.
Its push-pull output directly drives CMOS or TTL logic without an external pull-up resistor. The shutdown function can reduce activity or gate the comparator when a measurement path is inactive.
The exact AIDR order code is the SOIC-8 large-reel version. It should not be confused with slower low-power comparators such as TLV3201, whose design target is tens of microamps rather than maximum speed.

Functional Highlights
Nanosecond propagation supports edge/timing discrimination
Fast test, clock recovery and zero-crossing circuits can respond within a few nanoseconds when sufficient overdrive is available.
Push-pull output avoids open-collector RC delay
Both rising and falling logic edges are actively driven, which preserves speed into typical digital input capacitance.
Design Considerations
- Use very short input/output traces and controlled grounding to prevent output-to-input coupling and oscillation.
- Evaluate propagation delay at the actual input overdrive rather than only quoting the headline value.
- Do not wire push-pull outputs together as an open-collector wired alarm bus.
