CXA1866Q
Digital output polarity inversion input.
This is an ECL level input.
This input inverts the polarity of the
digital outputs P1D0 to P1D5, and
P2D0 to P2D5. (Refer to the Output
Code Table.)
When left open, this signal is
maintained at the low level.
These pins are for the 6 bits of digital
output data for DMPX port 1. P2D5 is
the MSB, and P2D0 is the LSB.
These are TTL level outputs.
These pins are for the 6 bits of digital
output data for DMPX port 2. P2D5 is
the MSB, and P2D0 is the LSB.
These are TTL level outputs.
+5V power supply for TTL level
internal circuit.
+5V power supply for TTL level
output buffers (P1D0 to P2D5).
