LTC6994IS6-1#WTRMPBF

Overview

The LTC6994IS6-1#WTRMPBF is a programmable delay block from the TimerBlox family, housed in a 6-lead TSOT-23 package. It provides a delay range of 1µs to 33.6 seconds, configured via a single resistor (RSET) and an internal clock divider (NDIV). The device operates on a single supply voltage between 2.25V and 5.5V with a typical supply current of 70µA at a 10µs delay. It features a CMOS output driver capable of sourcing and sinking 20mA. The component is qualified for automotive applications under AEC-Q100 standards and supports operation within a temperature range of -40°C to +85°C.

Feature Summary

• Configurable delay functionality allowing selection of rising or falling edge delays through the DIV pin logic setting.
• Dynamic adjustment capability enabling real-time modification of delay time via a separate control voltage input.
• Automotive-grade qualification ensuring reliability and performance consistency for demanding vehicle environments.

Applications

• Noise discriminators and pulse qualifiers for signal conditioning
• Switch debouncing circuits
• Delay matching in timing-critical systems

Procurement Notes

Verify the specific suffix #WTRMPBF indicates automotive grade tape and reel packaging. Confirm that the IS6 designation corresponds to the industrial temperature range of -40°C to +85°C. Ensure the ordering information matches the required quantity per mini-reel specifications provided by Analog Devices.

Selection Notes

Select this part when a wide delay range up to 33.6 seconds is required in a compact surface-mount package. Choose the -1 variant if only one transition edge requires delaying. Ensure the application environment meets the specified operating temperature limits and that the supply voltage remains within the 2.25V to 5.5V window.

Part Context

This component belongs to the LTC6994 series, which includes variants like the LTC6994-2 that delay both edges and offer output inversion. The IS6-1 suffix specifically denotes the industrial temperature grade and the single-edge delay configuration within the TimerBlox family of silicon timing devices.

Replacement Considerations

LTC6994IS6-1#TRMPBF serves as a standard commercial version without the automotive W suffix. For dual-edge delay requirements, consider the LTC6994IS6-2#WTRMPBF variant.
