PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
The TXS0101-Q1 device uses two separate configurable power-supply rails, VCCA and VCCB. VCCB accepts any supply voltage from 1.65V to 5.5V and VCCA accepts any supply voltage from 1.2V to 3.6V. The A port and B port are designed to track VCCA and VCCB respectively allowing for low voltage bidirectional translation between any of the 1.8V, 2.5V, 3.3V, and 5V voltage nodes.
The TXS0101-Q1 device does not require power sequencing between VCCA and VCCB during power-up so the power-supply rails can be ramped in any order. A VCCA value greater than or equal to VCCB (VCCA ≥ VCCB) does not damage the device, and during operation, VCCA may be greater than or equal to VCCB (VCCA ≤ VCCB).
The output-enable (OE) input circuit is designed so that it is supplied by VCCA and when the (OE) input is low, all outputs are placed in the high-impedance state. To put the outputs in the high-impedance state during power up or power down, the OE input pin must be tied to GND through a pulldown resistor and must not be enabled until VCCA and VCCB are fully ramped and stable. The current-sourcing capability of the driver determines the minimum value of the pulldown resistor to ground.
