NOTES: 2. ICCH is measured after applying a momentary ground, then 4.5 V, to the clock input with all data inputs at 4.5 V and the enable input at GND. 3. ICCL is measured after applying a momentary ground, then 4.5 V, to the clock input with all data and enable inputs at GND. timing requirements VCC = 5 V, TA = 25°C VCC = 4.5 V to 5.5 V, TA = MIN to MAX§ UNIT MIN MAX MIN MAX fclock Clock frequency 0 110 0 110 MHz tw Pulse duration 4 5 ns ↑ Data high or low 2 2 tsu Setup time before CLK ↑ CE high 2.5 2.5 ns CE low 4 4.5 th Hold time after CLK ↑ Data high or low 1 1 ns th Hold time after CLK ↑ CE high or low 0 0 ns § For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions. |
