Χαρακτηριστικά

TTL logic requires boards to operate at 5V logic levels, which was a standard for older microcontrollers and development boards. Even today, most sensors, development boards, and digital circuits run on a 5V power supply, allowing for easy integration with other circuits without the need for voltage shifting. However, with the advent of CMOS technology, most modern microcontrollers now operate at 3.3V logic levels, offering advantages such as lower power dissipation, faster switching, and higher reliability.

The 8-channel bi-directional logic level converter module is designed to shift 3.3V logic signals to 5V and vice versa. It is particularly useful for connecting older sensor circuits to newer, more powerful 3.3V boards like the Nano, BeagleBone Black, and Raspberry Pi.

For translating between 3.3V and 5V systems:

VCCA connects to the 3.3V power supply
VCCB connects to the 5V power supply
GND connects to the negative pole of the power supply; both power supplies must be common-grounded
When Ax receives a TTL 3.3V input, Bx outputs a TTL 5V signal
When Bx receives a TTL 5V input, Ax outputs a TTL 3.3V signal

Application examples

Communication between MCUs and 5V/3.3V modules
MCU to serial device interfacing
MCU to SD card communication

Technical data

Features

Enables the use of 5V modules with 3.3V microcontrollers or 3.3V modules with 5V microcontrollers
Does not support analog signals
While designed for open-drain applications, it can also translate push-pull CMOS logic outputs
8 channels for connecting and converting 8 logic lines
Bi-directional operation, eliminating the need for additional control inputs
No power supply sequencing required; VCCA or VCCB can be powered up first
Two working modes: enabled and disabled
When the output enable input (OE) is low, all outputs enter the high-impedance (Hi-Z) state
VCCA supports voltages from 1.2V to 3.6V
VCCB supports voltages from 1.65V to 5.5V
Supports common level conversions: 3.3V to 5V, 1.8V to 3.3V, etc.
Compatible with SCM, I²C, and SPI protocols
Compact design
