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
Rated for -25°C to 85°C operating.
Sourcing and lifecycle — active, no LTB risk
The LM293H is listed as Active in production. That means no last-time-buy clock is running, and you can qualify it into a new design without worrying about a sudden EOL notice. Texas Instruments continues to manufacture this part, and it is available through independent distribution channels.
