VCC Range for commercial –10 ns is 3.3 V ±150 mV. 5. Input signals switch from 0 V to 3 V with a rise/fall time of less than 3 ns, clocks and clock enables switch at maximum frequency of 20 MHz, while data inputs switch at 10 MHz. Outputs are unloaded. 6. All inputs = VCC – 0.2 V, except WCLK and RCLK (which are at frequency = 0 MHz). All outputs are unloaded. 7. Tested initially and after any design or process changes that may affect these parameters. [+] Feedback |
