The PCAL6408A is an 8-bit general-purpose I/O expander that provides remote I/O expansion for most microcontroller families via the I2C-bus interface. NXP I/O expanders provide a simple solution when additional I/Os are needed while keeping interconnections to a minimum, for example, in battery-powered mobile applications for interfacing to sensors, push but.
I2C-bus to parallel port expander
Operating power supply voltage range of 1.65 V to 5.5 V
Allows bidirectional voltage-level translation and GPIO expansion between:
1.8 V SCL/SDA and 1.8 V, 2.5 V, 3.3 V or 5 V Port P 2.5 V SCL/SDA and 1.8 V, 2.5 V, 3.3 V or 5 V Port P 3.3 V SCL/SDA and 1.8 V, 2.5 V, 3.3 V or 5 V Port P 5 V SCL/SDA and 1.8 V, 2.5 V, 3.3 V or 5 V Port P
Low standby current consumption of 1 A
Schmitt-trigger action allows slow input transition and better switching noise immunity at the SCL and SDA inputs Vhys = 0.18 V (typical) at 1.8 V Vhys = 0.25 V (typic.
