Description

Analog output.

The digital clamp circuit comprises

a D/A converter whose outputs are

available on these pins.

Analog +5 V power supply.

Normally open.

Pull-down resistors are

incorporated.

Output enable input.

When these pins are Low, data is

output from the digital output pins.

When these pins are High, the

digital output pins are high

impedance.

The A, B and C channels can be

controlled separately.

Also, these pins are not

synchronized with the clock signal.

Pull-down resistors are

incorporated.

Determines the digital output

mode. See the Mode Tables and

Timing Charts.

Pull-down resistors are

incorporated.

Controls the digital output mode

switching timing. The mode is

switched by detecting the transition

point where this pin changes from

Low to High. See the Mode

Tables and Timing Charts for

details.

A pull-down resistor is

incorporated.
