LTC6994CDCB-2#TRPBF

Overview

The LTC6994CDCB-2#TRPBF is a programmable delay block from the TimerBlox family, housed in a 6-Lead (2mm x 3mm) Plastic DFN package. It operates on a single supply voltage ranging from 2.25V to 5.5V with a specified temperature range of 0°C to 70°C. The device provides a delay range of 1µs to 33.6 seconds, determined by an internal master oscillator and a programmable clock divider (NDIV). It features a CMOS output driver capable of sourcing or sinking 20mA.

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
• Integrated noise discrimination and pulse qualification logic

Applications

• Noise discriminators and pulse qualifiers
• Switch debouncing circuits
• Delay matching applications

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when placing orders. Confirm that the 'C' grade designation aligns with the required commercial operating temperature range of 0°C to 70°C for your specific application environment.

Selection Notes

Select this model for applications requiring both rising and falling edge delays within the commercial temperature range. Ensure the external RSET resistor tolerance meets accuracy requirements, as delay precision depends heavily on the resistor value and the internal divider settings selected via the DIV pin.

Part Context

This component belongs to the Analog Devices LTC6994 series, which includes variants like the LTC6994-1 that delay only one edge type. The -2 suffix specifically denotes the ability to delay both transitions and offers output inversion options, distinguishing it from the -1 version in the same DFN package family.

FAQ

How is the delay time programmed?

The delay is set using a single resistor connected between the SET pin and GND, combined with a voltage divider on the DIV pin to select the clock division ratio.

What is the maximum output current?

The CMOS output driver can source or sink up to 20mA.
