LTC6994IS6-2#WTRPBF

Overview

The LTC6994IS6-2#WTRPBF is a programmable delay block from the TimerBlox family, housed in a 6-lead Plastic 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 10µs delay. It features a CMOS output driver capable of sourcing or sinking 20mA. The IS6 suffix indicates an industrial temperature grade ranging from -40°C to +85°C.

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 pulse width filtering
• Output polarity inversion option available for the -2 version

Applications

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

Procurement Notes

Verify the specific ordering suffix #WTRPBF against official Analog Devices documentation to confirm tape and reel packaging and automotive-grade manufacturing controls. Ensure the component meets the required environmental specifications for the intended deployment environment before finalizing procurement orders.

Selection Notes

Select this model when both rising and falling edge delays are required along with optional output inversion. Verify that the operating temperature range of -40°C to +85°C aligns with system requirements. Confirm that the SOT-23 package dimensions fit the PCB layout constraints.

Part Context

This component belongs to the LTC6994 series within the TimerBlox family of silicon timing devices. It shares core architecture with variants offering different temperature grades and package types, such as DFN or wider industrial ranges. The -2 designation specifically enables dual-edge delay and inversion capabilities not present in the -1 variant.

Replacement Considerations

Direct substitutes include other LTC6994 variants with compatible pinouts and electrical characteristics. Verify temperature ratings and package styles when selecting alternatives from the same product family.
