Description
Analog ground.
Separated from the digital ground.
Analog power supply.
Separated from the digital power
supply.
Digital ground.
Digital power supply.
Digital power supply.
Ground for ECL input.
+5V for PECL and TTL inputs.
Digital power supply.
–5V for ECL input.
Ground for PECL and TTL inputs.
Data output switching.
Data is output from both the PA side
and PB side by setting this pin open.
When set to DVcc1 level, only the
PA side output port outputs the data,
makes the PB side high impedance.
When set to DGND1 level, only the
PB side output port outputs the data,
makes the PA side high impedance.

Clamp
voltage
DVCC2 TTL output high level clamp.
The TTL high level voltage is
3k
clamped to the approximately same
value as the voltage applied to this
pin.

Even if this pin is left open, the TTL
3.5k
high level is clamped to
DGND2 approximately 2.8V.
