typical output is well below 0.4 V and the P82B96 typically requires 0.6 V input even
at +60 °C, so there is a reasonable margin. The PCA9601/PCA9600 requires a typical
input low of 0.5 V so its typical margin is smaller. At 0 °C the driver requires a typical
input low of 1.16 V and P82B96 provides 0.75 V, so again the typical margin is
already quite big and even though PCA9601/PCA9600 is better, providing 0.7 V, that
difference is not big.
