TCA6416APWR

The TCA6416APWR is a low-voltage 16-bit I²C and SMBus I/O Expander can operate with a power supply voltage on the I²C bus side (VCCI) and a power supply voltage on the P-port side (VCCP). The device supports both standard-mode and fast-mode clock frequencies. I/O expanders such as the TCA6416A provide a simple solution when additional I/Os are needed for switches, sensors, push-buttons, LEDs, fans, etc.

• I²C to parallel port expander
• Allows bidirectional voltage-level translation and GPIO expansion
• Low standby current consumption
• Active-low reset input
• Open-drain active-low interrupt output
• Input/output configuration register
• Polarity inversion register
• Internal power-on reset
• Green product and no Sb/Br

警告

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