YINGHUA LM293DR2G Comparator

The YINGHUA LM293DR2G is an analog comparator supplied in an SOIC-8 surface-mount package. It is a standard semiconductor component used for voltage comparison tasks in electronic circuits. This part is intended for engineers and technicians building or repairing analogue signal chains.

Suitable for comparator circuits

This device suits designs requiring a dual comparator in an SOIC-8 footprint. It is not for applications needing a different pin count, package style, or comparator topology. Buyers who need a single comparator, a quad comparator, or a through-hole package should look at other parts.

Dual comparator in SOIC-8

The defining specification is the dual comparator function housed in an SOIC-8 package. This combination of channel count and package type determines whether the part matches the schematic and board layout. Verify both parameters against your design before ordering.

Questions about this item

Will the LM293DR2G analog comparator work with legacy 5 V logic circuits I already have?

The LM293DR2G is a dual differential comparator in an SOIC-8 package; its open-collector outputs can interface with 5 V logic when pulled up to the same rail, so it fits older 5 V boards without level shifters.

How can I verify the LM293DR2G is functioning correctly after soldering it to the PCB?

Apply a known differential voltage to each input pair and measure the corresponding output switching low or high; the two independent channels should change state cleanly at the expected threshold.

Does the LM293DR2G reel include any passive components or must I source resistors and capacitors separately?

The reel contains only the LM293DR2G SOIC-8 comparators; all pull-up resistors, bypass capacitors and feedback networks have to be purchased separately.
