Signal Connection Descriptions
Pin Signal Name Direction Description
1–2 AIGND — Analog Input Ground—These pins are connected to the analog
input ground signal.
3–18 ACH<0..15> Input Analog Input Channels 0 through 15—These channels are in
single-ended mode.
19 DGND — Digital Ground—This pin is connected to the digital ground
signal.
20–21 NC — Not Connected—These pins are not connected.
22–29 DIN<0..7> Input Input Digital Data Lines 0 through 7—DIN7 is the MSB,
DIN0 the LSB.
30–37 DOUT<0..7> Output Output Digital Data Lines 0 through 7—DOUT7 is the MSB,
DOUT0 the LSB.
38 OUT1* Output Counter 1 Output—This pin is the inversion of counter 1
output.
39 EXTINT* Input External Interrupt—This pin is used for input of the external
interrupt signal.
40 EXTCONV* Input External Control—This pin is used for input of the external
control signal to trigger A/D conversions.
41 OUT0 Output Counter 0 Output—This pin is the output of counter 0.
42 GATE0 Input Counter 0 Gate Input—This pin is the gate input for counter 0.
43 OUT1 Output Counter 1 Output—This pin is the output of counter 1.
44 GATE1 Input Counter 1 Gate Input—This pin is the gate input for counter 1.
45 CLK1 Input Counter 1 Clock Input—This pin is the clock input for
counter 1.
46 OUT2 Output Counter 2 Output—This pin is the output of counter 2.
47 GATE2 Input Counter 2 Gate Input—This pin is the gate input for counter 2.
48 CLK2 Input Counter 2 Clock Input—This pin is the clock input for
counter 2.
49 +5 V Output +5 Volts—This pin provides +5 VDC. The +5 V supply is
fused at 1 A, which is the maximum current available.
50 DGND — Digital Ground—This pin is connected to the digital ground
signal.
