Input Leakage Current
Note: In Table 1 below, x refers to the characteristics described in table 2. For example, I1U indicates a pull-up resistor with a type 1
input characteristic.

Type Parameter Symbol
Note: The minimum pull-up resistor resistance meets the PCMCIA PC Card specification of 10k ohms but is intentionally higher in the
CompactFlash Specification to reduce power use.

MIN
Notes: 1) The host provides a logic output high voltage for a CMOS load of .9 x VCC. For a 5 volt product, this translates to .9 x
4.5 = 4.05 volts minimum Voh.
Output Drive Type
Note: In Table 3 below, x refers to the characteristics described in Table 4. For example, OT3 refers to Totem pole output with a type
3 output drive characteristic.
