LTC6994HS6-2#TRPBF

Overview

The LTC6994HS6-2#TRPBF 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 supports an operating temperature range of –40°C to 125°C. The device provides a delay range of 1µs to 33.6 seconds, configured via a master oscillator set by RSET and a programmable divider N_DIV (1 to 221). It features a CMOS output driver capable of sourcing or sinking 20mA, with a typical supply current of 70µA at 10µs delay. The part is AEC-Q100 qualified for automotive applications.

Feature Summary

• Programmable delay block with dynamic adjustment capability via control voltage
• Configurable to delay rising edge, falling edge, or both transitions
• Includes output inversion option for the -2 variant
• Automotive grade qualification for high reliability environments

Applications

• Noise discriminators and pulse qualifiers
• Switch debouncing circuits
• Delay matching in timing systems
• Portable and battery-powered equipment

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the HS grade corresponds to the required industrial temperature range of –40°C to 125°C for your application environment. Ensure the TSOT-23 footprint matches your PCB layout constraints. Check for any recent product change notifications that might affect pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select the LTC6994HS6-2#TRPBF when both rising and falling edges require delay and output inversion is needed. The HS grade ensures performance across the extended industrial temperature range. Verify that the required delay resolution and accuracy meet the system specifications, considering the tolerance of the external RSET resistor and the inherent delay accuracy of the device.

Part Context

This component belongs to the Analog Devices TimerBlox family of silicon timing devices. It shares the core architecture with the LTC6994-1 but offers enhanced functionality by delaying both signal transitions. The HS6 designation specifies the high-temperature grade and the TSOT-23 surface-mount package, distinguishing it from DFN variants or lower temperature grades within the same series.

Replacement Considerations

LTC6994HS6-2#TRMPBF is a verified substitute offering identical electrical and functional specifications in a mini-tape and reel format.
