The LVCH16260A tri-port bus exchanger has three 12-bit ports. Data may be transferred between the A port and either/both of the B ports. The latch enable (LE1B, LE2B, LEA1B and LEA2B) inputs control data storage. When a latch-enable input is high, the latch is transparent. When a latchenable input is low, the data at the input is latched and remains latched until the latch enable input is returned high. Independent output enables (OE1B and OE2B) allow reading from one port while writing to the other port. All pins of the 12-bit Bus Exchanger can be driven from either 3.3V or 5V devices. This feature allows the use of the device as a translator in a mixed 3.3V/5V supply system. |
