The TXS0108EPWR from Texas Instruments is an 8-bit, non-inverting, bidirectional level translator. It utilizes two separate configurable power-supply rails, allowing for flexible voltage translation between 1.4V and 3.6V on the A port (VCCA) and 1.65V to 5.5V on the B port (VCCB). This device does not require a direction-control signal, simplifying design.
Key features include maximum data rates of 110 Mbps for push-pull applications and 1.2 Mbps for open-drain applications. It offers robust ESD protection, exceeding JESD 22 standards on the A port and IEC 61000-4-2 on the B port. Latch-up performance is also a strong point, exceeding 100mA per JESD 78, class II.
This translator is suitable for various applications including handsets, smartphones, tablets, and desktop PCs. It is available in a 20-TSSOP package, designed for surface mounting. The device operates within a temperature range of -40°C to 85°C.
No power-supply sequencing is required, as either VCCA or VCCB can be ramped first. When the output-enable (OE) input is low, all outputs are placed in a high-impedance (Hi-Z) state, which can be achieved by tying OE to GND through a pull-down resistor.
