Detailed Terminal Descriptions
Please see Table 26 through Table 224 for more detailed terminal descriptions. The following list defines
the column headings and the abbreviations used in the detailed terminal description tables.
I/O Type:
I = Digital input
O = Digital output
I/O = Digital input/output
AI = Analog input
PWR = Power
GND = Ground
Input/Output Description:
AF = Analog feedthrough
TTLI1 = 5-V tolerant TTL input buffer
TTLI2 = 5-V tolerant TTL input buffer with hysteresis
TTLO1 = 5-V tolerant lownoise 4mA TTL output buffer
PCII1 = 3.3-V PCI input buffer
PCII3 = Universal 5-V tolerant PCI input buffer
PCII4 = 5-V tolerant PCMCIA input buffer
PCII5 = 5-V Smart Card input buffer
PCII6 = 5-V tolerant PCMCIA input buffer, failsafe
PCII7 = 5-V tolerant PCIMCIA input buffer
PCIO1 = 3.3-V PCI output buffer
PCIO3 = Universal 5-V tolerant PCI output buffer
PCIO4 = 5-V tolerant PCMCIA output buffer
PCIO5 = 5-V Smart Card output buffer
PCIO6 = 5-V Smart Card output buffer

TP = 1394a transceiver
PU/PD signifies whether the terminal has an internal pullup or pulldown resistor. These pullups are
disabled and enabled by design when appropriate to preserve power.
PD1 = 20-
A pulldown
PD2 = 100-
A pulldown
PU2 = 100-
A pullup
PU4 = 5-V tolerant 100-
A pullup
PU5 = 100-
A pullup
