TS334IDT

Overview

The TS334IDT is a quad micropower low-voltage comparator from STMicroelectronics, part of the TS33x series. It operates with a supply voltage ranging from 1.6 V to 5 V and features rail-to-rail inputs. The device consumes a typical current of 20 μA and offers a propagation delay of 210 ns. It has an open-drain output capable of sourcing 22 mA per channel. The input offset voltage is 5 mV, with input bias currents of 40 nA. It functions within a temperature range of -40 °C to +125 °C and is housed in a TSSOP-14 package.

Feature Summary

• Rail-to-rail inputs suitable for low-voltage applications
• Micropower operation with 20 μA current consumption
• Open-drain output configuration

Applications

• Low-voltage signal conditioning
• Space-constrained designs requiring tiny packages
• Automotive qualified systems

Procurement Notes

Verify the specific suffix 'DT' corresponds to the TSSOP-14 package and reel/cut-tape availability as listed in distributor catalogs. Confirm RoHS compliance status through official documentation. Ensure the ordering code matches the quad-channel variant distinct from single or dual versions in the same family.

Selection Notes

Select this component when designing for low-voltage environments between 1.6 V and 5 V. The rail-to-rail input capability allows for maximum dynamic range in single-supply systems. Consider the 210 ns propagation delay for timing-sensitive applications. The open-drain output requires external pull-up resistors for proper logic level translation.

Part Context

The TS334IDT belongs to the TS33x family, which includes single (TS331), dual (TS332), and quad (TS334) comparators. This family is characterized by micropower consumption and low-voltage operation. The TS334 specifically provides four independent comparators in one package, optimizing board space compared to using multiple single-channel devices.

Replacement Considerations

Check for other TS334 variants with different package options such as SOIC or DIP if pin compatibility differs. Verify if alternative quad comparators from other manufacturers meet the 1.6 V minimum supply and 20 μA current specs.
