PACKAGE/ORDERING INFORMATION

Pin Number

Pin Name

Pin Function

1, 2

IN0, /IN0

Differential Input: These input pairs are the differential signal inputs to the device. They

3, 4

IN1, /IN1

accept differential AC- or DC-coupled signals as small as 100mV. Each pin of a pair internally

terminates to a VT pin through 50Ω. Note that these inputs will default to an indeterminate

state if left open. Please refer to the

“Input Interface Applications” section for more details.

16, 5

VT0, VT1

Input Termination Center-Tap: Each side of the differential input pair terminates to a VT

pin. The VT0 and VT1 pins provide a center-tap to a termination network for maximum

interface flexibility. See

“Input Interface Applications” section for more details.

SEL

This single-ended TTL/CMOS compatible input selects the inputs to the multiplexer. Note

that this input is internally connected to a 25k

Ω pull-up resistor and will default to a logic

HIGH state if left open.

No connect.

8, 13

VCC

Positive Power Supply: Bypass with 0.1

µF0.01µF low ESR capacitors. 0.01µF capacitor

should be as close to VCC pin as possible.

12, 9

Q, /Q

Differential Outputs: This 100k compatible LVPECL output pair is the output of the device.

Normally terminate with 50

Ω to V

CC – 2V. See “Output Interface Applications” section. It is

a logic function of the IN0, IN1, and SEL inputs. Please refer to the

“Truth Table” for

details.
