LTC6994CS6-1#TRMPBF

Overview

The LTC6994CS6-1#TRMPBF is a programmable delay block from the TimerBlox family, housed in a 6-lead TSOT-23 package. It provides a delay range of 1µs to 33.6 seconds, configured via a single RSET resistor and an internal divider (NDIV) selectable from 8 settings. Operating on a single supply of 2.25V to 5.5V, it draws as low as 55µA at 10µs delay. The device features a CMOS output capable of sourcing/sinking 20mA and operates within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Configurable delay timing using a single external resistor and internal clock divider
• Edge-controlled delay functionality for pulse qualification and noise filtering
• Low power consumption suitable for battery-operated applications
• CMOS output driver with high current capability

Applications

• Noise discriminators and pulse qualifiers
• Switch debouncing circuits
• Delay matching in signal paths
• Timing elements in portable equipment

Procurement Notes

Verify the specific suffix #TRMPBF indicates mini tape and reel packaging containing 500 units. Confirm the CS6 designation corresponds to the TSOT-23 package and the C grade specifies the 0°C to 70°C operating temperature range. Ensure compatibility with standard surface mount assembly processes for this small outline package.

Selection Notes

Select the LTC6994CS6-1 variant when only rising or falling edge delay is required, rather than both. Choose the C grade for commercial temperature environments. Verify that the required delay range fits within the 1µs to 33.6s limit defined by the RSET and NDIV combinations. Consider the TSOT-23 package size constraints for the PCB layout.

Part Context

This component belongs to the Analog Devices TimerBlox family of silicon timing devices. It is part of the LTC6994 series, which includes variants like the LTC6994-2 that delay both edges and offer inversion. The CS6-1 designation specifically identifies the commercial grade, single-edge delay version in the TSOT-23 package.

Replacement Considerations

Direct functional replacements include other parts within the LTC6994 family such as the LTC6994IS6-1#TRMPBF for extended temperature ranges or the LTC6994HS6-1#TRMPBF for automotive/high-temperature needs. Cross-family replacements require verifying similar delay ranges and package footprints.
