CD40109BPWRE4

Translators, Level Shifters Overview

The CD40109BPWRE4 is a quad low-to-high voltage level shifter manufactured by Texas Instruments. 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 from -55 °C to +125 °C. It utilizes a 16-lead thin shrink small-outline package (TSSOP) with a width of 4.40 mm. The component is RoHS compliant, lead-free, and classified under the CD40109B series.

Translators, Level Shifters Feature Summary

• Eliminates the requirement for high-voltage supply presence before applying low-voltage power or input signals
• Supports flexible sequencing of supply voltages and input signals without operational restrictions
• Enables bidirectional shifting capability between high-to-low and low-to-high levels depending on relative supply magnitudes

Translators, Level Shifters Applications

• Interfacing digital logic circuits operating at different voltage domains
• System designs requiring flexible power-up sequences for mixed-voltage components
• Applications where input signal swings exceed the local supply rail voltages

Translators, Level Shifters Procurement Notes

Verify that the ordering suffix matches the required packaging configuration. Confirm the specific moisture sensitivity level rating and peak reflow temperature parameters align with your assembly process requirements. Ensure compliance with relevant environmental directives such as RoHS standards before finalizing procurement specifications.

Translators, Level Shifters Selection Notes

Select this component when circuit design requires independent control over power-up sequences for different voltage rails. Consider its ability to handle input signals exceeding both supply voltages for complex interface scenarios. Evaluate the thermal performance characteristics against the maximum operating temperature limits defined in the datasheet.

Translators, Level Shifters Part Context

This part belongs to the CD40109B series of voltage level shifters produced by Texas Instruments. It is designed to bridge communication gaps between logic families operating at distinct voltage levels. The device provides four independent channels within a single integrated circuit package.

Translators, Level Shifters Replacement Considerations

CD40109BPWR serves as a direct alternative offering identical electrical characteristics and functionality within the same TSSOP-16 package format.
