LTC6994CS6-2#TRMPBF

Overview

The LTC6994CS6-2#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 draws 70µA at a 10µs delay setting. The device provides a delay range of 1µs to 33.6 seconds, programmed via an internal master oscillator set by RSET (50kΩ to 800kΩ) and a divider N_DIV (1 to 2^21). As the -2 variant, it delays both rising and falling edges and supports output inversion. Propagation delay is typically 10ns at 5.5V, with a CMOS output driver capable of sourcing/sinking 20mA.

Feature Summary

• Configurable edge-delay functionality for both rising and falling transitions
• Dynamic delay adjustment capability via control voltage or resistor programming
• Noise discrimination and pulse qualification features for signal integrity

Applications

• Noise discriminators and pulse qualifiers
• Switch debouncing circuits
• Delay matching in timing systems

Procurement Notes

Verify the specific suffix #TRMPBF indicates mini tape and reel packaging containing 500 units. Confirm the 'C' grade designation aligns with the required commercial operating temperature range of 0°C to 70°C. Ensure the source documentation explicitly lists this part number as available through authorized channels to avoid counterfeit components.

Selection Notes

Select the LTC6994CS6-2 variant when simultaneous delay of rising and falling edges is required. Choose the CS6 package for surface-mount applications requiring a low-profile TSOT-23 footprint. Verify that the 0°C to 70°C commercial temperature rating meets the system's environmental constraints before finalizing the design.

Part Context

This component belongs to the Analog Devices TimerBlox family of silicon timing devices. It shares architectural similarities with other LTC699x series parts but is distinct in its specific delay block configuration. The CS6-2 designation identifies the commercial grade, TSOT-23 package, and dual-edge delay functionality within the broader product line.

Replacement Considerations

LTC6994IS6-2#TRMPBF offers identical electrical performance with an extended industrial temperature range (-40°C to 85°C). LTC6994HS6-2#TRMPBF provides high-grade operation (-40°C to 125°C). Substitution requires verifying thermal requirements and ensuring pin compatibility remains unchanged.
