The TXB0104PWR from Texas Instruments is a 4-bit automatic bidirectional voltage-level translator in a 14-pin TSSOP package. With separate VCCA (1.2-3.6V) and VCCB (1.65-5.5V) supplies, it automatically senses direction on each of the 4 channels, making it ideal for SPI and other multi-line bus translation.<\/p>\n
