LM306D

Overview

The LM306D is a high-speed voltage comparator featuring differential inputs and a low-impedance output capable of sinking 100 mA. It includes two strobe inputs for precise timing control. The device offers an excellent speed-to-power combination with a propagation delay of 40 ns. It provides fanout to 10 Series 54/74 TTL loads and includes short-circuit and surge protection. The component operates within a temperature range of 0°C to 70°C and exhibits a voltage input offset of 5 mV at ±12 V.

Feature Summary

• High-speed differential comparison with low-impedance push-pull output
• Dual strobe capability for precise signal gating
• Robust output stage supporting 100 mA sink current
• Integrated short-circuit and surge protection mechanisms

Applications

• High-speed analog-to-digital conversion interfaces
• Precision timing circuits requiring gated signals
• TTL-compatible logic interfacing systems

Procurement Notes

Verify the specific suffix 'D' indicates the SOIC package variant when sourcing. Confirm automotive qualification status if required for your application, as standard versions may differ. Ensure the supplier provides valid traceability documentation for Texas Instruments components to guarantee authenticity and compliance with RoHS standards.

Selection Notes

Select this component when high-speed differential comparison is required alongside significant load driving capability. The dual strobe feature makes it suitable for applications needing precise temporal control over the output state. Consider the 40 ns propagation delay for timing-sensitive designs and verify thermal management requirements for the SOIC package within the specified operating temperature range.

Part Context

The LM306 series consists of single high-speed comparators designed for demanding analog signal processing tasks. The LM306D specifically denotes the plastic small-outline integrated circuit (SOIC) package version manufactured by Texas Instruments. This family is characterized by its ability to interface directly with TTL logic while maintaining fast response times and high accuracy.

Replacement Considerations

Consult official Texas Instruments substitution guides for verified equivalents. Cross-reference pinouts and electrical specifications carefully before replacing.
