Zarlink Semiconductor Inc.
* Outputs unloaded. Input pins 12 and 25 clocked at 2048 kHz. All other inputs at VSS.
Timing is over recommended temperature & power supply voltages (VDD=5V±5%, VSS=0V, TA=–40 to 85°C).
Typical figures are at 25
°C and are for design aid only: not guaranteed and not subject to production testing.
