3.3 VOLT ZERO DELAY LOW SKEW BUFFER ZERO DELAY BUFFER
IDT™ / ICS™
3.3 VOLT ZERO DELAY LOW SKEW BUFFER 4
ICS2305 REV E 081709
DC Electrical Characteristics
ICS2305M-XX, VDD = 3.3 V ±10%, Ambient Temperature -40 to +85° C(Industrial), (0-70° C Commercial)
Note 1: When there is no clock signal present at CLKIN, the ICS2305 will enter power down mode. The
PLL is stopped and the outputs are tri-state.
AC Electrical Characteristics
ICS2305M-1, VDD=3.3 V ±10%, Ambient temperature -40 to +85° C(Industrial), (0-70° C Commercial)
Note 2: With VDD at a steady rate and valid input at CLKIN.
