1. EN, DIR, PWM = HIGH
2. Internal band-gap voltage is valid for VBAT > 3V (not testable)
3. Valid for –40°C to +90°C
4. R
5. Tested during qualification only
6. For timing, see the formula in
7. External parasitic capacitive load together with pull-up resistor at RX defines the time t
8. If single-ended mode is used (SEM = HIGH): DATA is not used and VBAT / 2 instead of DATA is the internal reference for
9. Maximum voltage difference arises during slope, see
10. Parameters 4.16 to 4.19 are based on transmit voltage slopes at DATA and /DATA of 4V/µs ±50%
