LTC6994IS6-2#TRPBF

Overview

The LTC6994IS6-2#TRPBF is a programmable delay block and debouncer from the TimerBlox family, manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 2.25V to 5.5V. The device provides a programmable delay range of 1µs to 33.6 seconds, determined by an internal master oscillator frequency set by a resistor (RSET) and a programmable clock divider (NDIV). The IS6 suffix indicates an industrial temperature grade (-40°C to 85°C), while the -2 suffix designates the version that delays both rising and falling edges with optional output inversion. It is housed in a 6-lead Plastic TSOT-23 package.

Feature Summary

• Configurable edge-delay functionality for noise discrimination and pulse qualification
• Single-resistor programming capability for setting the time base
• CMOS output driver capable of sourcing and sinking up to 20mA

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Ensure the component meets the required environmental specifications for the intended application environment before finalizing procurement orders.

Selection Notes

Select the LTC6994IS6-2 variant when both rising and falling edge delays are required or when output inversion is necessary. The 'I' designation specifies the industrial operating temperature range. Confirm that the external resistor values selected for RSET and DIV fall within the recommended ranges to ensure accurate delay performance.

Part Context

This component belongs to the LTC6994 series of TimerBlox silicon timing devices. It shares functional similarities with other members of the family but is distinguished by its specific temperature grade and dual-edge delay capabilities. It serves as a versatile solution for precise timing control in compact surface-mount designs.

Replacement Considerations

Direct replacements include other variants within the LTC6994 family, such as the LTC6994HS6-2#TRPBF for extended temperature ranges or the LTC6994IDCB-2#TRPBF for DFN packaging. Verify pin compatibility and electrical characteristics before substitution.
