SPECIAL FEATURES

The COM-VT-CH8 is a versatile 8-channel, bidirectional

voltage translator that simplifies interfacing between

digital systems with dierent logic levels. With

automatic direction detection, it eliminates the need

for control signals and enables transparent, hassle-

free communication. This makes the module ideal

for embedded systems, development setups, mixed-

voltage prototypes, and educational projects where

signals must flow in both directions.

It supports a supply voltage range of 1.2 V to 3.6 V on

the A-side and 1.65 V to 5.5 V on the B-side, ensuring

compatibility with nearly all common logic families.

Developers can easily connect modern low-power

MCUs, FPGAs, and sensors to legacy peripherals or

controllers that require 5 V logic. With transfer rates

up to 100 Mbps, the COM-VT-CH8 is well suited for fast

interfaces such as SPI, UART, I²C, or GPIO signaling.

An integrated OE pin (Output Enable) allows all channels

to be enabled or disabled simultaneously. Combined

with Io support, it prevents unwanted reverse currents

when a supply is powered down—an important

feature in low-power and battery-driven systems.

For convenient integration, the module comes with

two matching 10-pin headers included but not pre-

soldered, giving users full flexibility: they can be

soldered for breadboard use, or omitted for direct

wiring. This adaptability makes the COM-VT-CH8

suitable for professional prototypes, lab use, and

educational kits alike.
