TCAL Agile I/O expanders offer a wide range of capabilities on the GPIO pins. These capabilities include programmable output drive strength, integrated pull-up and pull-down resistors, latchable inputs, maskable interrupts, interrupt status register, and programmable options for open-drain and push-pull outputs. TCAL devices are also pin-to-pin compatible with the former TCA variant of I/O expanders. TCAL's are direct upgrades over the TCA's by offering agile I/O capability, low supply voltage support (1.08 V to 3.6 V), all while supporting faster data rates (<1 MHz) and better cost designs due to newer process technology.
