The LM393APWRE4 is a dual differential analog comparator manufactured by Texas Instruments. It features an 8-pin TSSOP surface-mount package and operates within a supply voltage range of 2V to 36V. The device provides two independent channels with open-collector outputs compatible with CMOS and TTL logic families. Key electrical specifications include a maximum input offset voltage of 5mV, a typical quiescent current of 0.2mA per channel, and a propagation delay of 1.3µs. It functions reliably across an operating temperature range of 0°C to +70°C.
Verify the specific suffix 'E4' indicates lead-free composition and RoHS compliance status according to the manufacturer's latest documentation. Confirm the TSSOP-8 package dimensions match the target PCB footprint requirements. Ensure the component grade aligns with the required input offset voltage specifications for the intended application environment.
Select this component when a dual-channel solution is required in a compact surface-mount form factor. The wide supply voltage range supports various system architectures without requiring additional level translation. Verify that the open-collector output configuration suits the downstream logic interface requirements.
This part belongs to the LM393 family of dual comparators from Texas Instruments. It shares functional similarities with other variants like the LM393DRG4 but differs in packaging and specific manufacturing revisions. The family is widely used in general-purpose analog comparison tasks due to its low cost and broad availability.
Direct substitutes include LM393PWRE4 or LM393PWR. Cross-referencing with LM2903 or LM2903PWRE4 may be possible if pinout compatibility is confirmed.
