LTC6994IDCB-1#TRPBF

Overview

The LTC6994IDCB-1#TRPBF is a programmable delay block from the TimerBlox family, housed in a 6-lead (2mm × 3mm) plastic DFN package. It operates on a single supply voltage ranging from 2.25V to 5.5V with an operating temperature range of –40°C to 85°C. The device provides a delay range from 1µs to 33.6 seconds, programmed via a single resistor at the SET pin and a divider code at the DIV pin. It features a CMOS output driver capable of sourcing or sinking 20mA, with a typical supply current of 70µA at a 10µs delay.

Feature Summary

• Configurable delay functionality for rising or falling edges using a single external resistor
• Dynamic adjustment capability through a separate control voltage input
• Integrated digital filter for noise discrimination and pulse qualification
• Low power consumption suitable for battery-powered portable equipment

Applications

• Noise discriminators and pulse qualifiers
• Switch debouncing circuits
• Delay matching in timing systems
• Operation in high vibration or high acceleration environments

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the IDCB variant corresponds to the industrial temperature grade required for the application environment. Ensure the component matches the exact Analog Devices part number to guarantee compatibility with design specifications and automotive reliability standards if applicable.

Selection Notes

Select the LTC6994-1 version when only one edge transition requires delaying. Choose the LTC6994-2 variant if both rising and falling edges must be delayed or if output inversion is needed. Use the TimerBlox design tool to calculate precise resistor values for the desired delay time and divider settings based on the target supply voltage.

Part Context

This component belongs to the TimerBlox family of silicon timing devices manufactured by Analog Devices Inc. It serves as a versatile delay block alternative to traditional monostable multivibrators or discrete timing circuits. The device integrates master oscillator and clock divider functions into a compact surface-mount package for space-constrained designs.
