BTK1A and BTM1A
Electrical Characteristics
Table 4. Driver Voltage and Current Characteristics
For variations in output voltage over the temperature range, see Figure 10 and Figure 11. T
* Values are with terminations as per Figure 7.
† The input levels and difference voltage provide zero noise immunity and should be tested only in a static, noise-free environment.
‡ Test must be performed one lead at a time to prevent damage to the device.
