Two LVXC3245 — 8-bit non-inverting bus transceivers All inputs and outputs are 5V tolerant 2×5 male header connectors for solderless connections Minimum Input Edge Rate (dV/dT) 8 ns/V
This board features two 8-bit non-inverting bus transceivers, model LVXC3245. All inputs and outputs are 5V tolerant. LVXC3245 is manufactured in advanced dual-metal CMOS technology. This bus transceiver contains two separate supply rails that allow transition from a 3.3V to 5V system environment. This bus transceiver is ideal for asynchronous communication between two data buses (A and B). It transmits data from A to B or vice versa, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device, thus isolating the buses effectively.
The board is must be powered by 3.3V and 5V. The 3.3V supply comes from the development system, while the 5V DC supply comes from an external power supply source to the board's screw terminal.
The 3.3V-5V Voltage Translator Board is capable of bi-directional adjustment, meaning that voltage signals may be sent and received at the same time (from 3.3V to 5V and vice versa). In bi-directional mode, the position of jumpers depends on the voltage signal direction. For example, if voltage signals are sent from a development system (3.3V) via the LSV0 pin to a device (5V) via the HVS0 pin, it is necessary to place those pins' jumpers into the position marked →. At the same time, voltage signals may be sent from the device (5V) via HVS1 to the development system (3.3V) via LVS1, provided that those pins' jumpers are placed in the position marked ←. These rules apply to all jumpers on the board — LVS0-7 and HVS0-7.
