IOB Pad Input/Output/3-State Switching Characteristics

Tabl e 2 7 summarizes the values of standard-specific data

input delay adjustments, output delays terminating at pads

(based on standard and 3-state delays.

IOPI

is described as the delay from IOB pad through the

input buffer to the I-pin of an IOB pad. The delay varies

depending on the capability of the SelectIO input buffer.

IOOP

is described as the delay from the O pin to the IOB

pad through the output buffer of an IOB pad. The delay var-

ies depending on the capability of the SelectIO output

buffer.

IOTP

is described as the delay from the T pin to the IOB

pad through the output buffer of an IOB pad, when 3-state is

disabled. The delay varies depending on the SelectIO capa-

bility of the output buffer.

Table 2 8 summarizes the value of T

IOTPHZ

. T

IOTPHZ

described as the delay from the T pin to the IOB pad

through the output buffer of an IOB pad, when 3-state is

enabled (i.e., a high impedance state).
