PCA9538A
Low-voltage 8-bit I2C-bus I/O port with interrupt and reset
2. Features and benefits
I2C-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 VDD)
1.0 A (typical at 3.3 V VDD)
Schmitt-trigger action allows slow input transition and better switching noise immunity
at the SCL and SDA inputs
Vhys = 0.10 VDD (typical)
5 V tolerant I/Os
Active LOW reset input (RESET)
Open-drain active LOW interrupt output (INT)
400 kHz Fast-mode I2C-bus
Internal power-on reset
Power-up with all channels configured as inputs
No glitch on power-up
Latched outputs with 25 mA drive maximum capability for directly driving LEDs
Latch-up performance exceeds 100 mA per JESD78, Class II
ESD protection exceeds JESD22
2000 V Human Body Model (A114-A)
1000 V Charged-Device Model (C101)
Packages offered: TSSOP16 and HVQFN16
