Feature

This logic level converter features four high speed bi-directional 4 channels, allowing for safe and easy communication between devices operating at different logic levels. Converting between logic levels as low as 1.5 V on the lower-voltage side and as high as 18 V on the higher-voltage side.
Its four channels are enough to support most common bidirectional and unidirectional digital interfaces, including IC, SPI, and asynchronous TTL serial.
The logic high levels on each side of the shifter are achieved by 10 k pull-up resistors to their respective supplies; these provide quick enough rise times to allow decent conversion of fast mode (400 kHz) IC signals or other similarly fast digital interfaces (e.g. SPI or asynchronous TTL serial). External pull-ups can be added to speed up the rise time further at the expense of higher current draw.
This module comes with male header pins that require soldering.
NOTE : Voltage supplied to the HV and GND inputs should be higher than that supplied to the LV side; Level shifters are purely digital, they can't map an analog voltage from one max voltage to another.

Description

As digital devices get smaller and faster, once ubiquitous 5 V logic has given way to ever lower-voltage standards like 3.3 V, 2.5 V, and even 1.8 V, leading to an ecosystem of components that need a little help talking to each other. For example, a 5 V part might fail to read a 3.3 V signal as high, and a 3.3 V part might be damaged by a 5 V signal. This level shifter solves these problems by offering bidirectional voltage translation of up to four independent signals, converting between logic levels as low as 1.5 V on the lower-voltage side and as high as 18 V on the higher-voltage side, and its compact size and breadboard-compatible pin spacing make it easy to integrate into projects.
