5V-3.3V Voltage Translator Board

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.

IC/Module: LVXC3245 8-bit Configurable Dual Supply Transceiver

The LVXC3245 is a 24-pin dual-supply, non-inverting bus transceiver especially well-suited for PCMCIA, and other real time configurable I/O applications. The VCCA pin receives a 3V supply level. The A Port is a dedicated 3V port. The VCCB pin receives a 3V-to-5V supply level. The B Port is set up to track the VCCB supply level respectively. A 5V level on the VCC pin will configure the I/O pins at a 5V level and a 3V VCC will configure the I/O pins at a 3V level. The A Port should interface with a 3V host system and the B Port to the card slots. This device allows the VCCB voltage source pin and I/O pins on the B Port to float when OE# is HIGH. This attribute is necessary to buffer data to and from a PCMCIA socket that require live insertion and removal during normal operation.

Jumper Settings

The 5V-3.3V Voltage Translator Board uses two power supply voltages, wherein the 5V power is supplied from the development system, while the 3.3V power is either provided from the connected device on the other side or from the development system. The jumper J17 enables an MC33269DT-3.3 voltage regulator that will provide the 3.3V power from the 5V side. Furthermore, in order to enable 5V to 3.3V or 3.3V to 5V voltage signal adjustment, jumpers belonging to jumper groups DIR1 and DIR2 should be placed in appropriate positions.
