Product Description

The TCA9554APWR is an 8-bit remote I²C and SMBus I/O Expander provides 8-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. The device supports both 100kHz (standard-mode) and 400kHz (fast-mode) clock frequencies. The I/O expanders such as the TCA9554A provide a simple solution when additional I/Os are needed for switches, sensors, push-buttons, LEDs, fans and other similar devices. The features of the TCA9554A include an interrupt that is generated on the INT pin whenever an input port changes state. The A0, A1 and A2 hardware selectable address pins allow up to eight this device on the same I²C bus. The device can also be reset to its default sate by cycling the power supply and causing a power-on reset.
Open-drain active-low interrupt (INT)\ output
Three hardware address pins allow up to eight devices on the I²C/SMBus
Input/output configuration register
Polarity inversion register
Internal power-ON reset
Low standby current consumption
Power-up with all channels configured as inputs
No glitch on power-up
Noise filter on SCL/SDA input
Latched outputs with high-current drive maximum capability for directly driving LEDs
Latch-up performance exceeds 100mA per JESD 78, class II
5V Tolerant i/o ports
400kHz Fast I²C bus
Green product and no Sb/Br
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.
