Description

Anlog GND.

Used as GND for input

buffers and latches of

comparators.

Isolated from DGND or

DGND 1/2.

Analog VEE

–5.2V (Typ.).

Internally connected

with DVEE

(resistance: 4 to 6Ω).

Ceramic chip

capacitors of at least

0.1µF should be used

to connect to AGND

and be placed near

the pins.

CLK input

Input complementary

to CLK.

With open connection,

kept at threshold

voltage (–1.3V).

Device is operable

without CLK input, but

use of complementary

inputs of CLK and CLK

is recommended to

obtain the stable high-

speed operation.

internal circuits and

output transistors)
