Chip-Select—latch control for the digital inputs. When

–

C

—

S

–

is low, A0 and E

—

N

–

input registers are transparent. When C

—

S

–

goes high, the A0 input register latches.

If LE is high, the E

—

N

–

input register also latches when C

—

S

–

goes high (see LE).

Digital Latch-Enable Input. When LE is low, the E

—

N

–

register is transparent;

when LE is high, the E

—

N

–

register is transparent only when C

—

S

–

is low. Hard-

wire to V+ or GND for best crosstalk performance.

Channel-Select Input. When C

—

S

–

is low, driving A0 low selects channel A

and driving A0 high selects channel B.

Buffer-Enable Input. When C

—

S

–

is low or LE is low, driving E

—

N

–

low enables

all output buffers and driving E

—

N

–

high disables all output buffers.
