Description

Digital input.

30 pin D0 (LSB) to 7 pin D9 (MSB)

No connection.

Clock input.

Blanking input.

This is synchronized with the clock

input signal.

No signal (0 V output) at high and

output state at low.

Chip enable input.

This is not synchronized with the

clock input signal.

No signal (0 V output) at high makes

power consumption minimum.

Digital power supply.
