Product details

What this comparator brings to the board

The rail-to-rail CMOS push-pull output drives logic inputs directly. Quiescent current maxes out at 14 µA. Propagation delay is 1.8 µs maximum. That is not a high-speed comparator — you would not use it for a switching power supply loop or a high-frequency zero-cross detector. But for over-voltage/under-voltage monitoring, temperature threshold alarms, or window comparators on slow analog signals, the delay is well within margin. The SC-70-5 package is a 5-pin surface-mount footprint.

Pinout and replacement notes

The TLV9032DDFR is a dual-channel comparator in a similar speed class (100 ns propagation delay) with a wider temperature range (-40°C to 125°C) and lower input bias (5 pA). It is not a pin-compatible second source — different pinout and dual vs single channel — but it is the closest functional alternative if you need two comparators in one package and can re-lay the board.

Frequently asked questions

Where can I buy LMV7291MGX/NOPB?

This part is sourced to order through independent distribution. Submit an RFQ for current availability and pricing — confirmed at quote time.

Does LMV7291MGX/NOPB replace LMV7291MG?

Yes. The LMV7291MGX/NOPB is electrically identical to the LMV7291MG. The only difference is the packaging format: the NOPB suffix ships in tape and reel, while the LMV7291MG typically ships in tube or bulk.

What is the pinout of LMV7291MGX/NOPB?

The SC-70-5 pinout is: pin 1 output, pin 2 V-/GND, pin 3 non-inverting input, pin 4 inverting input, pin 5 V+.

What is the closest functional second-source to LMV7291MGX/NOPB?

The TLV9032DDFR is a dual-channel comparator with similar supply range and faster propagation delay (100 ns), but it is not pin-compatible. It is the closest functional alternative if you can accommodate a different footprint and need two channels.
