LM393P-P2

Overview

The LM393P-P2 is a commercial-grade dual differential voltage comparator manufactured by Texas Instruments. It features an open-collector output structure compatible with TTL, MOS, and CMOS logic levels. The device operates on a single supply ranging from 2V to 36V or dual supplies where the difference is between 2V and 36V. Key electrical parameters include a typical response time of 1.3µs, input offset voltage of 1mV, and static current of 200µA per comparator. It utilizes a PDIP-8 through-hole package with dimensions of 9.81mm x 6.35mm x 4.57mm and functions within a temperature range of 0°C to +70°C.

Procurement Notes

Verify that the specific suffix P2 corresponds to the standard PDIP-8 packaging and commercial grade specifications documented for the LM393P series. Confirm RoHS compliance and lead-free status as these are standard attributes for this component family but require validation against the specific manufacturer's ordering information for the P2 variant.

Selection Notes

Select this component when a low-cost, general-purpose dual comparator is required for single or dual supply applications. Ensure the design accommodates the open-collector output requirement by providing appropriate pull-up resistors. Verify that the 1.3µs response time meets the system speed requirements and that the operating temperature range aligns with the environmental conditions.

Part Context

The LM393P belongs to the widely used LM393 family of dual comparators known for their versatility in analog signal processing. This specific part number represents the through-hole PDIP-8 version intended for general commercial electronics. It serves as a fundamental building block for threshold detection and waveform generation in various electronic designs.

Replacement Considerations

Direct pin-compatible replacements within the same family include LM393DR (SOIC-8) and LM393TL (μSMD). For equivalent performance in different packages, consider LM393D or LM393N. Ensure any substitute maintains the open-collector output configuration and similar electrical characteristics.
