PCA9505规格书详情

description

The PCA9505/PCA9506 provide 40-bit parallel input/output (I/O) port expansion for I2C-bus applications organized in 5 banks of 8 I/Os. At 5 V supply voltage, the outputs are capable of sourcing 10 mA and sinking 15 mA with a total package load of 600 mA to allow direct driving of 40 LEDs. Any of the 40 I/O ports can be configured as an input or output. Output ports are totem-pole and their logic state changes at the Acknowledge (bank change). The PCA9505 is identical to the PCA9506 except that it includes 100 kΩ internal pull-up resistors on all the I/Os. The PCA9506 does not include the internal pull-ups on the I/Os to reduce power consumption when used as outputs or when the input is driven by a push-pull driver.

Features

■ Standard mode (100 kHz) and Fast mode (400 kHz) compatible I2C-bus serialinterface

■ 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 state change on Acknowledge

◆ Open-drain active LOW interrupt (INT) output pin allows monitoring of logic level change of pins programmed as inputs
