TS393CS RLG

Overview

The TS393CS RLG is a dual micro-power CMOS voltage comparator manufactured by Taiwan Semiconductor Corporation. It operates within a supply voltage range of 2.7 V to 16 V and draws a typical quiescent current of 6 µA per device. The component features an open-drain output configuration capable of sinking up to 20 mA, facilitating direct interfacing with various logic families including TTL and CMOS. Key electrical characteristics include a propagation delay of 5.8 µs, an input offset voltage of 1.4 mV, and an input bias current of 1 pA. It supports a common-mode rejection ratio of 71 dB and a power supply rejection ratio of 80 dB. The device is rated for operation across an extended temperature range from -40 °C to +125 °C and is housed in an SOIC-8 surface-mount package.

Procurement Notes

Verify the specific suffix 'RLG' against official Taiwan Semiconductor documentation to confirm packaging details such as reel size or tape width. Ensure the ordering part number matches the required SOIC-8 variant. Confirm RoHS compliance status through the manufacturer's latest datasheet revision. Cross-reference the date code and lot traceability requirements with your supply chain specifications before finalizing procurement orders.

Selection Notes

Select this component when low static power dissipation is critical alongside standard voltage comparator functionality. The wide supply voltage range allows compatibility with both single-supply and split-rail configurations. The open-drain output simplifies wired-OR connections and interface design with different logic families without requiring additional pull-up components beyond the necessary load resistor.

Part Context

This device belongs to the TS393 series of dual comparators, designed for general-purpose analog switching applications. It serves as a low-cost alternative to bipolar comparators while offering superior power efficiency. The CMOS technology ensures high input impedance and noise immunity, making it suitable for precision sensing tasks where minimal loading on the signal source is required.

Replacement Considerations

Check for pin-compatible alternatives within the same family that may offer updated packaging or enhanced thermal performance. Verify if other manufacturers provide equivalent dual comparators with similar propagation delays and supply voltage ranges. Ensure any substitute maintains the open-drain output characteristic and CMOS input compatibility.
