CD40109BE

Translators, Level Shifters Overview

The CD40109BE is a quad low-to-high voltage level translator 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 extended temperature range from -55 °C to +125 °C. Packaged in a 16-lead plastic dual-in-line (PDIP) format, it allows flexible sequencing of power supplies and input signals without restrictions on relative voltage magnitudes.

Translators, Level Shifters Feature Summary

• Eliminates the requirement for high-voltage supply presence before applying low-voltage power or input signals
• Supports bidirectional voltage magnitude flexibility where VCC may exceed VDD
• Provides tri-state outputs with non-inverting logic functionality

Translators, Level Shifters Applications

• Interfacing between different logic families requiring voltage translation
• Systems requiring flexible power-up sequencing for mixed-voltage domains
• High-speed digital signal conversion applications

Translators, Level Shifters Procurement Notes

Verify the specific package suffix against the datasheet to confirm physical dimensions and pinout compatibility. Ensure the ordering code matches the required lead finish and moisture sensitivity level ratings. Confirm RoHS compliance status if environmental regulations apply to the manufacturing process. Cross-reference the active production status with current availability channels.

Translators, Level Shifters Selection Notes

Select this component when designing circuits that require independent control over low and high voltage domains without strict power-up sequencing constraints. Consider the 16-lead PDIP package for through-hole mounting requirements. Evaluate the 100 ns propagation delay against system timing budgets. Verify that the operating temperature range meets the environmental conditions of the intended deployment.
