Electrical and Optical Specifications
Specifications (Min. and Max. values) hold over the recommended operating conditions unless otherwise noted.
Unspecified test conditions may be anywhere in their operating range. All typical values (Typ.) are at 25
°
C, Vcc set to 3.0V
and IOVcc set to 1.8V unless otherwise noted.

17. Latency time is defined as the time from the last TxD light output pulse until the receiver has recovered full sensitivity.
18. Receiver wake up time is measured from Vcc power on or SD pin high to low transition to a valid RXD output.
19. The maximum optical PW is the maximum time the LED remains on when the TXD is constantly high. This is to prevent long turn on time of the LED
for eye safety protection.
