Product details

Description

The PCA9505/PCA9506 provide 40-bit parallel input/output (I/O) port expansion for I2Cbus applications organized in 5 banks of 8 I/Os.

Features

Standard mode (100 kHz) and Fast mode (400 kHz) compatible I2C-bus serial interface.
2.3 V to 5.5 V operation with 5.5 V tolerant I/Os.
40 configurable I/O pins that default to inputs at power-up.
PCA9505 includes 100 kΩ internal pull-up resistors on all the I/Os.
Outputs:.
Totem-pole (10 mA source, 15 mA sink) with controlled edge rate output structure.
Active LOW output enable (OE) input pin 3-states all outputs.
Output s.
