LTC6994IS6-2#TRMPBF

Overview

The LTC6994IS6-2#TRMPBF is a programmable delay block from the TimerBlox family, housed in a 6-lead Plastic TSOT-23 package. It operates on a single supply voltage ranging from 2.25V to 5.5V and supports an operating temperature range of –40°C to 85°C. The device provides a delay range of 1µs to 33.6 seconds, configured via a single resistor (RSET) and a programmable divider (NDIV). It features a CMOS output driver capable of sourcing or sinking 20mA, with a typical supply current of 70µA at a 10µs delay.

Feature Summary

• Configurable delay functionality for rising edges, falling edges, or both transitions
• Dynamic adjustment capability via a separate control voltage input
• Noise discrimination and pulse qualification through minimum width filtering
• Low power consumption suitable for battery-operated applications

Applications

• Noise discriminators and pulse qualifiers
• Switch debouncing circuits
• Delay matching in signal paths
• Portable and battery-powered equipment

Procurement Notes

Verify the specific suffix #TRMPBF indicates mini tape and reel packaging when ordering. Confirm the IS6 designation corresponds to the industrial temperature grade and TSOT-23 package variant required for the target application environment. Ensure compatibility with the intended PCB footprint for the 6-lead thin profile package.

Selection Notes

Select the LTC6994-2 variant specifically if simultaneous delay of both rising and falling edges is required, as opposed to the -1 version which handles single-edge delays. Consider the NDIV settings available via the DIV pin to achieve the desired total delay range. Verify that the external RSET resistor tolerance meets the accuracy requirements for the specific delay interval.

Part Context

This component belongs to the Analog Devices TimerBlox family of versatile silicon timing devices. The LTC6994 series includes variants with different temperature grades and package options, such as DFN and various TSOT-23 configurations. The -2 suffix denotes the dual-edge delay functionality within this product line.
