Texas Instruments TCA9535RTWR TCA9535RTWR I/O Expander 16 bit I2C Smbus 1.65 V 5.5 Wqfn 24 Pins

The TCA9535RTWR is a 16-bit I²C and SMBus I/O Expander with interrupt output and configurable registers provides 16-bits of general purpose parallel input/output (I/O) expansion for the two-line bidirectional I²C bus or (SMBus) protocol. The device can operate with a power supply voltage ranging from 1.65 to 5.5V. I/O expanders, such as the TCA9535, provide general-purpose remote I/O expansion for most microcontroller families via the I²C interface, providing a simple solution when additional I/Os are needed for switches, sensors, push-buttons, LEDs, fans and other similar devices. It consists of two 8-bit configuration (input or output selection), input port, output port and polarity inversion (active-high or active-low operation) registers. At power on, the I/Os are configured as inputs. The system master can enable the I/Os as either inputs or outputs by writing to the I/O configuration bits.

• Open-drain active-low interrupt (INT)\ output
• Polarity inversion register
• Address by 3 hardware address pins for use of up to 8 devices
• Latched outputs with high-current drive capability for directly driving LEDs
• Latch-up performance exceeds 100mA per JESD 78, class II
• 3µA Maximum low standby-current consumption
• 400kHz Fast I²C bus
• Green product and no Sb/Br

Applications

Industrial, Automation & Process Control, Computers & Computer Peripherals, Communications & Networking

Warnings Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
