TLC393IPWRG4

Comparators Overview

The TLC393IPWRG4 is a dual micropower LinCMOS voltage comparator manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 16 V and draws a typical quiescent current of 40 uA. The device features an open-drain output capable of sinking up to 6 mA per channel. Key electrical specifications include a maximum response time of 4.5 us, an input offset voltage of 5 mV, and an input bias current of 5 pA. It provides a common-mode rejection ratio of 84 dB and supports differential input types. The component is housed in a TSSOP-8 surface-mount package and is rated for operation between -40 C and +125 C.

Comparators Feature Summary

• Utilizes LinCMOS technology to achieve low power consumption suitable for battery-operated applications.
• Features open-drain outputs that allow flexible interfacing with various logic families through external pull-up resistors.
• Designed for general-purpose analog comparison tasks with high common-mode rejection capabilities.

Comparators Applications

• Battery-powered monitoring systems requiring low standby current
• Threshold detection circuits in industrial control panels
• Over-voltage protection schemes in single-supply environments

Comparators Procurement Notes

Verify the specific suffix IPWRG4 to confirm the TSSOP-8 tape-and-reel packaging format. Ensure compatibility with the required operating temperature range of -40 C to +125 C for your application environment. Confirm RoHS compliance status as indicated in the official datasheet documentation before finalizing procurement orders.

Comparators Selection Notes

Select this component when a dual-channel comparator with ultra-low quiescent current is required. The open-drain output structure necessitates external pull-up components for proper logic level translation. Consider the 4.5 us propagation delay when designing high-speed signal processing paths, as it may limit performance in fast-switching applications compared to faster comparator alternatives.

Comparators Part Context

This part belongs to the TLC393 series of dual micropower comparators from Texas Instruments. It shares functional similarities with other variants in the family but differs in packaging and termination options. The IPWRG4 designation specifically identifies the TSSOP-8 surface-mount variant with lead-free plating and reel packaging, distinguishing it from PDIP or SOIC versions.

Comparators Replacement Considerations
