Pin Function
Differential Input Pairs: The inputs are internally biased to 1.2V.
LVPECL Differential Output Pairs.
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.
Source Select for OUT (TTL Input): Selects either IN0 (LOW) or IN1 (HIGH);
defaults HIGH when left open.
Source Select for OUT0 (TTL Input): Selects either IN (LOW) or IN0 (HIGH);
defaults HIGH when left open.
Source Select for OUT1 (TTL Input): Selects either IN (LOW) or IN1 (HIGH);
defaults HIGH when left open.
Positive Power Supply: Bypass with 0.1µF//0.01µF low ESR capacitors as close to
the V
Positive Output Power Supply: Bypass with 0.1µF//0.01µF low ESR capacitors as
close to the VCCPx pins as possible. Supplies the respective output buffers.
Ground: Exposed pad must be connected to a ground plane that is the same
potential as the ground pins.
CC
pin as possible. Supplies input and core circuitry.
