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.
No connected pin.
Not connected with the internal
circuits.
Clock input.
CLK/E complementary input.
When left open, this pin goes to the
threshold voltage.
Only CLK/E can be used for
operation, but complementary inputs
are recommended to attain fast and
stable operation.
Reset signal input.
When set to low level, the built-in
CLK frequency divider circuit can be
reset.
RESETN/E complementary input.
When left open, this pin goes to the
threshold voltage. Only RESETN/E
can be used for operation.
