CD40109BNSR

Translators, Level Shifters Overview

The CD40109BNSR is a CMOS 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 reliably across an operating temperature range from -55 °C to +125 °C. It is housed in a 16-lead Small Outline Package (SOP) with an NSR suffix, designed for surface-mount applications.

Translators, Level Shifters Feature Summary

• Supports flexible power sequencing without requiring the high-voltage supply to be applied before the low-voltage supply or input signals.
• Capable of bidirectional shifting modes; when operated with VCC exceeding VDD, it functions as a high-to-low level shifter.
• Allows input signal swings that exceed both VCC and VDD levels, provided they remain within absolute maximum ratings.

Translators, Level Shifters Applications

• Interfacing between different logic families such as TTL and CMOS
• Translating voltage levels between distinct CMOS domains
• Bidirectional level shifting in mixed-voltage digital systems

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'NSR' to confirm the 16-lead SOP package type and tape-and-reel carrier format. Ensure the procurement matches the catalog status and material specifications listed in the official TI documentation. Cross-reference the part marking against the addendum to validate authenticity and traceability.

Translators, Level Shifters Selection Notes

Select this component when a quad unidirectional or bidirectional voltage translator is required for mixed-voltage environments. Consider the wide operating temperature range and robust input tolerance characteristics suitable for industrial applications. Verify that the SOP package dimensions align with the target PCB layout constraints.

Translators, Level Shifters Part Context

This device belongs to the CD4000B series of CMOS logic devices produced by Texas Instruments. It serves as a specialized interface solution for bridging voltage gaps between disparate digital logic standards. The NSR suffix specifically denotes the small-outline package variant supplied in large tape-and-reel quantities for automated assembly processes.

Translators, Level Shifters Replacement Considerations

Qualified versions include the automotive-grade CD40109B-Q1 and military-certified CD40109B-MIL. Other package options within the same family are available, such as the PDIP (BE), TSSOP (PW/PWR), and ceramic DIP (BF) variants.
