Notes:

1/ VCC = 5.0 Volts dc +/-0.1 Volts dc unless otherwise specified.

2/ All specifications and limits are for a single channel with no connections made to the other channel.

3/ Parameters shall be tested as part of device initial characterization and after design and process

changes. Parameter shall be guaranteed to limits specified in above tables for all lots not specifically

tested.

4/ Threshold determined by first no response to a receive 32 word command.

5/ Measured 2.5µSec after the mid-bit zero crossing of the last parity bit of a 660µSec transmission.
