Description
1
VSS Ground.
2-5 D0i-D3i Input/Microport Data Bus. This is part of a 16 bit data bus. The data bus is bidirectional in
Connect Memory mode where it is typically interfaced to a microprocessor. In all other
modes the data bus is an input. Data to be switched through the device is clocked in at this
port.

VSS Ground.
D4i-D7i Input/Microport Data Bus. See description for pins 2-5 above.
11
VSS Ground.
12-15 D8i-D11i Input/Microport Data Bus. See description for pins 2-5 above.
16
VSS Ground.
17-20 D12i-D15i Input/Microport Data Bus. See description for pins 2-5 above.
21
VSS Ground.
22
CK Clock. Master clock input which is used to clock data into and out of the device. It also clocks
the internal 11 bit counter.

VDD +5V supply input.
VSS Ground.
IC Internal Connection. Should be tied to VSS for normal operation.
FP Frame Pulse. An active low signal that serves as a synchronous clear for the internal 11 bit
counter in all modes except Shift Register mode. The counter is cleared on a rising edge of
CK. In the Shift Register mode, FP serves to align channel boundaries.
