LTC6994MPS6-1#TRM

Overview

The LTC6994MPS6-1#TRM is a programmable delay block from the TimerBlox family, manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 2.25V to 5.5V and features an operating temperature range of –55°C to 125°C. The device provides a programmable delay range from 1µs to 33.6 seconds, determined by a master oscillator frequency set via RSET and an internal clock divider NDIV. It is housed in a 6-Lead Plastic TSOT-23 package with SMD/SMT installation style. The CMOS output driver can source and sink up to 20mA.

Feature Summary

• Configurable delay functionality for rising or falling edges using a single resistor for time base programming
• Dynamic adjustment capability via separate control voltage input
• Automotive qualification compliant with AEC-Q100 standards
• Low power consumption suitable for battery-powered applications

Applications

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

Procurement Notes

Verify the specific suffix #TRM indicates tape and reel packaging when ordering. Confirm the MPS6 designation corresponds to the extended industrial/automotive temperature grade of –55°C to 125°C. Ensure compatibility with the 6-Lead Plastic TSOT-23 footprint during PCB layout. Check for any automotive reliability reports if deploying in qualified automotive applications.

Selection Notes

Select the LTC6994-1 variant specifically for applications requiring delay of only one transition edge (rising or falling). Choose this model over the -2 version if output inversion is not required. Verify that the required delay range fits within the 1µs to 33.6 seconds specification. Consider the 20mA output drive capability for direct load interfacing without additional buffering.

Part Context

This component belongs to the TimerBlox family of versatile silicon timing devices produced by Analog Devices Inc. It serves as a precision programmable delay line alternative to discrete RC networks. The MPS6 suffix denotes the military/extended temperature grade variant within the TSOT-23 package lineup, distinct from commercial or standard industrial grades.

Replacement Considerations

LTC6994MPS6-1#TRMPBF is the mini-tape and reel equivalent. LTC6994IS6-1#TRMPBF offers the same function but with a restricted –40°C to 85°C operating range.
