Product details

Dual comparator in a TO-99-8 can — what you're getting

The LM293H is a general-purpose dual comparator from Texas Instruments. Two independent comparators share a common supply range of 2V to 36V (or ±1V to ±18V dual). Outputs are open-collector, compatible with CMOS, DTL, ECL, MOS, and TTL families. Propagation delay is 700ns max. Quiescent current maxes at 2.5mA per package. Output sink current is 16mA at 5V.

Package and mounting — TO-99-8 metal can

The LM293H comes in a TO-99-8 metal can, a through-hole hermetic package.

Temperature grade — -25°C to 85°C

Frequently asked questions

Is LM293H a dual comparator?

Yes, the LM293H contains two independent general-purpose comparators in a single TO-99-8 package.

What is the output type of LM293H?

Outputs are open-collector, compatible with CMOS, DTL, ECL, MOS, and TTL logic families. An external pull-up resistor is required to set the logic-high level.
