A. See mechanical drawings for dimensions.
B. Pullup resistors are not required on both sides for Logic I/O.
C. If pullup or pulldown resistors are needed, the resistor value must be over 50kΩ.
D. 50kΩ is a safe recommended value, if the customer can accept higher VOL or lower VOH, smaller pullup or pulldown resistor is allowed, the draft estimation is VOL = VCCOUT × 4.5k / (4.5k + RPU) and VOH = VCCOUT × RDW / (4.5k + RDW).
E. If pull up resistors are needed, please refer to the TXS0101 or contact TI.
F. For detailed information, please refer to application note, A Guide to Voltage Translation With TXB-Type Translators.
Pin Functions
PIN TYPE DESCRIPTION
NO. NAME
1 VCCA — A-port supply voltage. 1.2V ≤ VCCA ≤ 3.6V and VCCA ≤ VCCB
2 GND — Ground
3 A I/O Input/output A. Referenced to VCCA.
4 B I/O Input/output B. Referenced to VCCB.
5 OE I 3-state output enable. Pull OE low to place all outputs in 3-state mode.
Referenced to VCCA.
6 VCCB — B-port supply voltage. 1.65V ≤ VCCB ≤ 5.5V
