CD40109BPWRG4

Translators, Level Shifters Overview

The CD40109BPWRG4 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 in an industrial temperature range from -55°C to +125°C. It utilizes a 16-lead Thin Shrink Small-Outline Package (TSSOP) with surface-mount installation.

Translators, Level Shifters Feature Summary

• Supports bidirectional voltage translation between low-voltage and high-voltage domains without requiring specific power-up sequencing.
• Capable of operating as a high-to-low level shifter when the low-voltage supply exceeds the high-voltage supply.
• Provides tri-state, non-inverting outputs for flexible bus interfacing.

Translators, Level Shifters Applications

• Interfacing microcontrollers with higher voltage peripherals

Translators, Level Shifters FAQ

Does the CD40109 require the high-voltage supply to be applied before the low-voltage supply?

No, unlike other low-to-high level-shifting circuits, it does not require the presence of the high-voltage supply before applying the low-voltage supply or input signals.

Can the CD40109 operate as a high-to-low level shifter?

Yes, when operated in the mode where the low-voltage supply exceeds the high-voltage supply, the device functions as a high-to-low level shifter.
