3.3V-5V Voltage Translator Board
The 3.3V-5V Voltage Translator Board is a bidirectional voltage translator that comes integrated with two 8-bit, dual supply, configurable voltage interface transceivers, model LVXC3245. Made using dual metal CMOS technology, the LVXC3245 module includes two separate supply rails that allow transition from a 3.3V to 5V system environment. The 3.3V-5V Voltage Translator Board allows user to adjust voltage levels of a development system sending 3.3V voltage signals and receiving 5V voltage signals. All the inputs and outputs are 5V tolerant. Ideal for asynchronous communication between two data buses (A and B), this bus transceiver transmits data from A to B or vice versa, based 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 3.3V-5V Voltage Translator Board is well-suited for PCMCIA configurable I/O applications and makes an ideal choice for low power designs. It also meets all PCMCIA I/O voltage requirements at 5V and 3.3V operation.
5V-3.3V Reg Board
Provide a stable and reliable 3.3V and 5V power supply to the device using the 5V-3.3V Reg Board. This regulator board features a LM7805 3-terminal 5V positive voltage regulator and a MC33269 3.3V low dropout positive voltage regulator to provide fixed supply voltages. The board features two voltage input options, which includes a screw terminal connector CN2 and AC/DC adapter connector CN1 (8 to 16V AC/DC). An on-board voltage regulator is used to reduce and stabilize the supplied voltage. The reduced voltage may be either 3.3V or 5V and is delivered via screw terminals CN3 (5V) and CN4 (3.3V). For 5V voltage, the maximum current amounts to 1A, whereas for 3.3V voltage, it amounts to 800 mA. Furthermore, 5V-3.3V Reg Board is provided with mounting holes for easy integration into the design. The board has a diode bridge of four 1N4007 diodes that performs as a rectifier when using an AC input, and as polarity protection when using a DC input.
The 5V-3.3V Reg Board is very handy for systems that demand a regulated 3.3V or 5V power supply.
5V-3.3V Voltage Translator Board
The 5V-3.3V Voltage Translator Board features two LVXC3245 8-bit, dual supply non-inverting voltage interface transceivers. Made using dual metal CMOS technology, the LVXC3245 module includes two separate supply rails that allow transition from a 5V to 3.3V system environment. The 5V-3.3V Voltage Translator Board allows user to adjust voltage levels between a 5V development system and a 3.3V device. All the inputs and outputs are 5V tolerant. Ideal for asynchronous communication between two data buses (A and B), this bus transceiver transmits data from A to B or vice versa, based on the logic level at the Direction-Control (DIR) input. The onboard MC33269DT-3.3 voltage regulator can be enabled using a jumper J17 to create 3.3V power for the Low-Voltage Port, if the device is not capable of providing the 3.3V power supply voltage.
The 5V-3.3V Voltage Translator Board is well-suited for PCMCIA and other real time configurable I/O applications and also makes an ideal choice for low power designs. It also meets all PCMCIA I/O voltage requirements at 5V and 3.3V operation.
