ФУНКЦИИ

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:

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 = 0.18 V (typical) at 1.8 V

Vhys = 0.25 V (typical) at 2.5 V

Vhys = 0.33 V (typical) at 3.3 V

Vhys = 0.5 V (typical) at 5 V

5 V tolerant I/O ports

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

Noise filter on SCL/SDA inputs
