Anmbest 5PCS 4 Chanels High Speed Bi-Directional 3.3V-5V Logic Level Converter for Arduino Raspberry Pi Electronic Development
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 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 map 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)
Features:
- 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 k 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.
