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 input.

Digital power supply.

–5V for ECL input.

Ground for PECL and TTL input.

No connected pin.

Not connected with the internal

circuits.

Clock input.

CLK/E complementary input.

When left open, this pin goes to the

threshold potential.

Only CLK/E can be used for

operation, but complementary input

is recommended to attain fast and

stable operation.

Reset input.

When the input is 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.
