PIN TYPE DESCRIPTION
NAME NO.
A 3 I/O Input or output A. This pin is referenced to VCCA. When this pin is configured as an input, do not leave it floating.
B 4 I/O Input or output B. This pin is referenced to VCCB. When this pin is configured as an input, do not leave it floating.
DIR 5 I Direction control signal. Set to Logic High for A-to-B level translation. Set to Logic Low for B-to-A level translation.
GND 2 — Ground.
VCCA 1 — A-port supply voltage. 0.65 V ≤ VCCA ≤ 3.6V.
VCCB 6 — B-port supply voltage. 0.65 V ≤ VCCB ≤ 3.6V.
