PIN TYPE(1) DESCRIPTION
NAME NO.
A 3 I/O Output level depends on VCC1 voltage
B 4 I/O Input threshold value depends on VCC2 voltage
DIR 5 I GND (low level) determines B-port to A-port direction
GND 2 G Device GND
VCCA 1 P SYSTEM-1 supply voltage (1.65V to 5.5V)
VCCB 6 P SYSTEM-2 supply voltage (1.65V to 5.5V)
(1) G = Ground, I = Input, O = Output, P = Power
