CD40109BPWR

Translators, Level Shifters Overview

The CD40109BPWR is a quad low-to-high voltage level translator manufactured by Texas Instruments in the 4000B series. It operates within a supply voltage range of 3 V to 18 V and supports data rates up to 10 Mb/s. The device features a propagation delay of 100 ns and functions across an operating temperature range of -55°C to +125°C. Packaged in a 16-lead Thin Shrink Small-Outline Package (TSSOP), it utilizes large tape-and-reel packaging for automated assembly.

Translators, Level Shifters Feature Summary

• Enables bidirectional voltage translation between low-voltage and high-voltage logic domains without requiring specific power-up sequencing.
• Supports flexible operation where the low-voltage supply can exceed the high-voltage supply, allowing the device to function as a high-to-low level shifter.
• Provides four independent unidirectional channels with tri-state outputs for efficient bus management.

Translators, Level Shifters Applications

• Interfacing low-voltage microcontrollers with high-voltage peripheral devices
• Bidirectional translation between different logic families in mixed-signal systems
• Level shifting in communication interfaces requiring flexible voltage domain adaptation

Translators, Level Shifters Procurement Notes

Verify that the ordering suffix matches the required package type and moisture sensitivity level. Confirm RoHS compliance status and lead finish specifications against project requirements. Ensure the supplier provides valid traceability documentation. Check for any specific automotive or military qualification designations if applicable to the target environment.

Translators, Level Shifters Selection Notes

Select this component when interfacing circuits with disparate voltage levels that lack strict power-up sequencing constraints. The TSSOP package is suitable for space-constrained surface-mount designs. Consider the 100 ns propagation delay and 10 Mb/s data rate limits to ensure compatibility with system timing requirements.

Translators, Level Shifters Part Context

This part belongs to the CD40109B family of voltage translators from Texas Instruments. It is designed to bridge logic families operating at different voltage potentials. The 'PWR' suffix specifically denotes the 16-lead TSSOP package configuration supplied in a large tape-and-reel format for high-volume manufacturing.

Translators, Level Shifters Replacement Considerations

Direct substitutes include CD40109BPW and CD40109BPWE4, which share identical electrical characteristics but differ in packaging form factor or environmental compliance markings.
