Timing Specifications
Note 5: Values for 8 full-duplex (decoding and encoding) or 16 half-duplex (decoding or encoding) channels operation in a 125 µs period.
Unless otherwise noted, limits printed in bold characters are guaranteed for V
−40˚C to +85˚C by correlation with 100% electrical testing at T
production tests and/or product design and characterization. Typical values are specified at V
