Description

CONVERT DIFFERENT LOGIC LEVELS: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. SUITABLE FOR MULTIPLE INTERFACES: Its four channels are enough to support most common bidirectional and unidirectional digital interfaces, including I²C, SPI, and asynchronous TTL serial. FAST CONVERSION: The logic high levels on each side of the shifter are achieved by 10 kΩ pull-up resistors to their respective supplies; these provide quick enough rise times to allow decent conversion of fast mode (400 kHz) I²C 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. UNIVERSAL COMPATIBILITY: Module compatible breadboard, can be directly inserted in the breadboard to use. ATTENTION:This module comes with male header pins that require soldering..

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 bi-directional voltage translation of up to four independent signals, and its compact size and breadboard-compatible pin spacing make it easy to integrate into projects. Technical Specifications: Dual-supply bus translation : Lower-voltage (LV) supply can be 1.2 V to 3.6 V Higher-voltage (HV) supply can be 1.65 to 5.5 V Four bi-directional channels Small size: 15 mm × 13 mm/0.59″ × 0.51″(L×W) Breadboard-compatible pin spacing Voltage input pins : 2 pins (GND and LV) on Low Voltage side; 2 pins (GND and HV) on High Voltage side Data channels : 4 pins (LV1, LV2, LV3, and LV4) on Low Voltage side; 4 pins (HV1, HV2, HV3, and HV4) on High Voltage side 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 an analog voltage from one max voltage to another. Package includes: 5 x 4 Chanels High speed Bi-Directional 3.3V-5V Logic Level Converter Each set contains: 1x Logic Level Converter；2x Single Row Pin Header(6 pins)
