1. VDD_VH_IOx = 3.3 V -5%,+10%, TJ = –40 / 150 °C, unless otherwise specified

2. Startup time is defined as the time taken by LFAST current reference block for settling bias current after its pwr_down

(power down) has been deasserted. LFAST functionality is guaranteed only after the startup time.

3. Startup time is defined as the time taken by LFAST transmitter for settling after its pwr_down (power down) has been

deasserted. Here it is assumed that current reference is already stable. LFAST functionality is guaranteed only after the

startup time.

4. Startup time is defined as the time taken by LFAST transmitter for settling after its pwr_down (power down) has been

deasserted. Here it is assumed that current reference is already stable. LFAST functionality is guaranteed only after the

startup time.

5. Startup time is defined as the time taken by LFAST receiver for settling after its pwr_down (power down) has been

deasserted. Here it is assumed that current reference is already stable. LFAST functionality is guaranteed only after the

startup time.
