OE0
OE1
Output Enable (TTL Inputs): OEx pins enable OUTx pins when HIGH. When OEx is
LOW, OUTx are powered down and both OUT and /OUT go HIGH.
3
MUX
Source Select for OUT (TTL Input): Selects either IN0 (LOW) or IN1 (HIGH);
defaults HIGH when left open.
16
MUX0
Source Select for OUT0 (TTL Input): Selects either IN (LOW) or IN1 (HIGH);
defaults HIGH when left open.
15
MUX1
Source Select for OUT1 (TTL Input): Selects either IN (HIGH) or IN0 (LOW);
defaults HIGH when left open.

VCC
Positive Power Supply: Bypass with 0.1F//0.01F low ESR capacitors as close to
the VCC pin as possible. Supplies input and core circuitry.

VCCP1
Positive Output Power Supply: Bypass with 0.1F//0.01F low ESR capacitors as
close to the VCCPx pins as possible. Supplies the respective output buffers.
4, 7, 14, 25
GND,
Exposed pad
Ground: Exposed pad must be connected to a ground plane that is the same
potential as the ground pins.
