PCA9601

Dual bidirectional bus buffer

• When the operating temperature range is restricted at both limits. An I2C driver's

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.
