The TXB0304 is a 4-bit voltage level translator for push-pull applications. The A port is designed to track VCCA. VCCA accepts any supply voltage from 0.9 V to 3.6 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 0.9 V to 3.6 V. This allows for low-voltage bidirectional translation anywhere between the 0.9-V and 3.6-V voltage nodes.
The TXB0304 EVM was created to allow simplified evaluation and prototyping without the need for full board development. This EVM provides peripheral header style pads for probing and signal connection to each device pin. Headers are labeled with the corresponding pin name.
