PCA9538A
Low-voltage 8-bit I
2
C-bus I/O port with interrupt and reset
2. Features and benefits
 I
2
C-bus to parallel port expander
 Operating power supply voltage range of 1.65 V to 5.5 V
 Low standby current consumption:
 1.5 A (typical at 5 V V
DD
)
 1.0 A (typical at 3.3 V V
DD
)
 Schmitt-trigger action allows slow input transition and better switching noise immunity
at the SCL and SDA inputs
 V
