LTC6994CS6-2#TRPBF

Overview

The LTC6994CS6-2#TRPBF 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 with an operating temperature range of 0°C to 70°C. The device provides a delay range from 1µs to 33.6 seconds, determined by a master oscillator and an internal divider (NDIV) selectable from 1 to 2^21. It features a CMOS output driver capable of sourcing and sinking 20mA. Key electrical parameters include a typical propagation delay of 10ns at 5.5V, a supply current of approximately 70µA at 10µs delay, and a start-up time of 500µs.

Feature Summary

• Configurable delay functionality for rising or falling edges via the DIV pin polarity setting
• Dynamic delay adjustment capability through a separate control voltage input
• Noise discrimination and pulse qualification features for signal integrity

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging rather than mini-tape and reel. Confirm the CS6 designation corresponds to the commercial temperature grade and TSOT-23 package. Ensure compatibility with the required delay range and supply voltage specifications for the target design.

Selection Notes

Select this model when a commercial temperature range is sufficient. The -2 suffix indicates both rising and falling edges are delayed. Use the TimerBlox design tool to calculate RSET and DIV resistor values for precise timing. Consider the HS6 variant if automotive qualification or extended temperature ranges are required.

Part Context

This component belongs to the Analog Devices TimerBlox family of silicon timing devices. It shares architectural similarities with other parts in the series but is distinct in its specific delay block configuration. The CS6 package offers a low-profile surface mount solution suitable for space-constrained designs.

Replacement Considerations

LTC6994HS6-2#TRMPBF: Automotive qualified version with extended temperature range. LTC6994IS6-2#TRMPBF: Industrial temperature grade version. Note that suffix changes may affect temperature rating or packaging type.
