TS3022IST

Overview

The TS3022IST is a dual high-speed comparator from STMicroelectronics, housed in an 8-pin MiniSO package. It operates on a supply voltage ranging from 1.8V to 5V. The device features rail-to-rail inputs and push-pull outputs. Typical propagation delay is 9ns, with a maximum of 38ns. Quiescent current per comparator is approximately 73µA. Input offset voltage is typically 6mV at 5V. Operating temperature range spans from -40°C to +125°C.

Feature Summary

• Rail-to-rail input capability allows operation across the full supply voltage range.
• Push-pull output structure provides strong drive capability without external pull-up resistors.
• High-speed response combined with low power consumption optimizes efficiency for battery-powered applications.

Applications

• Portable consumer electronics requiring fast signal processing with minimal power draw.
• Battery-operated systems utilizing single-supply operation.
• General-purpose analog signal conditioning circuits.

Procurement Notes

Verify the specific suffix 'IST' corresponds to the MiniSO-8 package and industrial temperature grade (-40°C to +125°C). Confirm that the ordering code matches the required tape-and-reel or cut-tape quantity specifications. Ensure compatibility with the target PCB footprint dimensions for the 8-MiniSO package before finalizing procurement orders.

Selection Notes

Select this component when both high speed and low power are critical constraints. The rail-to-rail input feature simplifies biasing in single-supply designs. Compare propagation delay and quiescent current requirements against other family members like the TS3021 if only a single channel is needed. Verify that the push-pull output meets the load requirements of the subsequent stage.

Part Context

The TS3022IST belongs to the TS3022 series of micropower comparators. This series is designed for applications demanding a balance between speed and energy efficiency. It complements single-channel variants within the same product line, offering integrated dual functionality in a compact surface-mount package suitable for space-constrained designs.

Replacement Considerations

The TLV3202AIDGK from Texas Instruments is identified as a similar alternative. Verify pinout compatibility and electrical parameter alignment before substitution. Ensure the replacement package matches the existing board layout constraints.
