LTC6994IDCB-2#TRMPBF

Overview

The LTC6994IDCB-2#TRMPBF is a programmable delay block and debouncer from the TimerBlox family, housed in a 6-lead DFN package. It provides a delay range of 1µs to 33.6 seconds, configured via a single RSET resistor (50kΩ to 800kΩ) and an internal divider N_DIV (1 to 221). The device operates on a single supply voltage of 2.25V to 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 -2 suffix indicates it delays both rising and falling edges and supports output inversion.

Feature Summary

• Configurable delay functionality for rising and/or falling signal transitions
• Dynamic adjustment capability via external control voltage
• Integrated noise discrimination and pulse qualification logic
• Single-resistor programming interface for master oscillator frequency

Applications

• Noise discriminators and pulse qualifiers
• Switch debouncing circuits
• Delay matching applications
• High vibration or high acceleration environments

Procurement Notes

Verify the specific ordering suffix #TRMPBF confirms the tape and reel mini packaging format. Confirm the 'I' grade designation matches the required industrial operating temperature range of –40°C to 85°C. Ensure the DCB package type aligns with the target PCB footprint requirements.

Selection Notes

Select the LTC6994-2 variant specifically when both rising and falling edge delays are required. Use the DIV pin configuration to enable output inversion if necessary. Ensure the RSET resistor tolerance meets the accuracy requirements for the desired delay range.

Part Context

This component belongs to the Analog Devices TimerBlox family of silicon timing devices. It serves as a versatile solution for precise time-based signal manipulation within mixed-signal systems requiring low power consumption and compact packaging.

Replacement Considerations

LTC6994IDCB-2#PBF: Identical functional specifications but supplied in tube packaging instead of tape and reel.
