LTC6994IS6-2#WTRMPBF

Overview

The LTC6994IS6-2#WTRMPBF 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 from 1µs to 33.6 seconds, determined by a master oscillator frequency set via an external resistor (RSET) and an internal clock divider (NDIV). The LTC6994-2 variant delays both rising and falling edges and allows output inversion. It features a CMOS output driver capable of sourcing or sinking 20mA.

Feature Summary

• Configurable delay functionality for one or both signal transitions with optional output inversion
• Dynamic delay adjustment capability through a separate control voltage input
• Integrated noise discrimination and pulse qualification logic

Applications

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

Procurement Notes

Verify automotive grade status by confirming the #W suffix indicates controlled manufacturing for automotive reliability requirements. Ensure the IS6 designation matches the required industrial temperature range of –40°C to 85°C. Confirm the -2 suffix aligns with the need for dual-edge delay and inversion capabilities. Validate the TSOT-23 package dimensions against PCB layout constraints.

Selection Notes

Select this part when dual-edge delay and output inversion are required within the industrial temperature range. The -2 suffix distinguishes it from the -1 version which only delays a single edge. Consider the NDIV settings and RSET values to achieve the specific delay time. Verify that the 20mA output drive current meets load requirements without exceeding absolute maximum ratings.

Part Context

This component belongs to the Analog Devices TimerBlox family of versatile silicon timing devices. It shares core architecture with other LTC6994 variants but differs in package type, temperature grade, and specific delay functionality defined by the suffix codes. The IS6-2 designation specifies the industrial temperature grade, TSOT-23 package, and dual-edge delay/inversion feature set.

Replacement Considerations

LTC6994IS6-2#TRMPBF is the standard commercial tape and reel equivalent without the automotive #W suffix.
