Icc (max) is specified at the output open condition. 2. Address can be changed once or less while /RAS = VIL. 3. Address can be changed once or less while /CAS = VIH CAPACITANCE ( T A=25 o C, Vcc = 5V+/- 10%, f = 1Mhz ) DESCRIPTION SYMBOL MIN MAX UNITS NOTE Input Capacitance (A0-A9) CI1 - 5 pF 1 Input Capacitance (/WE,/RAS, /CAS0- /CAS3,/OE) C I2 - 7 pF 1,2 Input/Output Capacitance (DQ0-31) CDQ1 - 7 pF 1,2 Note: 1. Capacitance measured with Boonton Meter or effective capacitance measuring method. 2. /CAS = VIH to disable DOUT.
