Pin Function
accept differential AC- or DC-coupled signals as small as 100mV. Each pin of a pair internally
terminates to a V
state if left open. Please refer to the “Input Interface Applications” section for more details.
Input Termination Center-Tap: Each side of the differential input pair terminates to a V
pin. The V
interface flexibility. See “Input Interface Applications” section for more details.
This single-ended TTL/CMOS compatible input selects the inputs to the multiplexer. Note
that this input is internally connected to a 25ký pull-up resistor and will default to a logic
HIGH state if left open.
No connect.
Positive Power Supply: Bypass with 0.1µF™™0.01µF low ESR capacitors. 0.01µF capacitor
should be as close to V
Normally terminate with 50ý to V
a logic function of the IN0, IN1, and SEL inputs. Please refer to the “Truth Table” for
details.
Ground. Ground pins and exposed pad must be connected to the same ground plane.
Differential Input: These input pairs are the differential signal inputs to the device. They
Differential Outputs: This 100k compatible LVPECL output pair is the output of the device.
