TXB0104 Voltage-Level Translator Breakout

Product Features
A port is 1.2V to 3.6V, B port is 1.65V to 5.5V (VCCA ≦ VCCB)
VCC Isolation Function - All outputs are in a high-impedance state if the VCC input is at GND
OE input circuit reference VCC
Low power, 5μA max ICC
product description

This 4-bit non-inverting converter uses two separate configurable power rails. Port A is designed to track VCCA. VCCA accepts any supply voltage from 1.2V to 3.6V. Port B is used to track VCCB. The VCCB accepts any supply voltage from 1.65V to 5.5V. This allows a common low voltage bidirectional conversion between 1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5V voltage nodes. VCCA should not exceed VCCB. We have broken every pin of this module and you have easy access to A and B ports.
