Input Leakage Control; Input Characteristics; Output Drive Type - SanDisk CompactFlash Product Manual

3.3.1. Input Leakage Control

NOTE: In Table 3-3 x refers to the characteristics described in Section 3.3.2. For example, I1U indicates a pull up
resistor with a type 1 input characteristic.
Type Parameter
IxZ Input Leakage Current
IxU Pull Up Resistor
IxD Pull Down Resistor
NOTE: The minimum pullup resistor leakage current meets the PCMCIA specification of 10k ohms but is
intentionally higher in the CompactFlash Memory Card Series product to reduce power use.

3.3.3. Output Drive Type

In Table 3-5 x refers to the characteristics described in Section 3.3.4. For example, OT3 refers to Totempole output
with a type 3 output drive characteristic.
