LTC6994HS6-1#TRMPBF

Overview

The LTC6994HS6-1#TRMPBF 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 single resistor (RSET) and a programmable divider (NDIV). Key electrical parameters include a typical propagation delay of 14ns at 3.3V, a maximum output current of ±20mA, and a supply current as low as 70µA at 10µs delay.

Feature Summary

• Configurable edge-delay functionality allowing selection between rising or falling transition delays
• Noise discrimination capabilities through pulse qualification logic
• Dynamic delay adjustment via external control voltage or resistor programming

Applications

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

Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel mini packaging when sourcing. Confirm the HS grade corresponds to the required industrial temperature range for your environment. Ensure compatibility with the 6-lead TSOT-23 footprint during PCB layout review.

Selection Notes

Select this model for applications requiring extended high-temperature operation up to 125°C. The -1 variant specifically delays either the rising or falling edge, not both simultaneously. Verify that the required delay resolution and accuracy meet the system specifications before finalizing the design.

Part Context

This component belongs to the Analog Devices LTC6994 series, which includes variants like the LTC6994-2 that delay both edges and offer inversion. The HS6-1 designation specifies the high-temperature grade and surface-mount TSOT-23 packaging, distinguishing it from DFN or standard commercial grade options within the same functional family.

Replacement Considerations

LTC6994IS6-1#TRMPBF offers identical functionality but with a lower industrial temperature rating of –40°C to 85°C.
