TCAL I/O expanders are direct upgrades to the TCA I/O expanders. TCAL is pin-to-pin compatible with TCA of the same part number. For example, TCAL6408 is the direct upgrade to the TCA6408. Here are some of the benefits of using a TCAL I/O expander over a TCA I/O expander.
Table 8-1 shows the current available TCAL I/O expanders offered by TI.
