PACKAGE/ORDERING INFORMATION
Pin Number
Pin Name
Pin Function
1, 4
IN0, /IN0
Differential Inputs: These inputs accept AC- or DC-coupled signals as small as 100mV.
5, 8
IN1, /IN1
Each pin of a pair internally terminates to a VT pin through 50. Note that these
25, 28
IN2, /IN2
inputs will default to an indeterminate state if left open. If an input pair is not used, connect
29, 32
IN3, /IN3
one input of the pair to ground through a 1k resistor and the complement to VCC through a
825 resistor. Unused VT and VREF-AC may also be left open. Please refer to the “Input
Interface Applications” section for more details.
2, 6, 26, 30
VT0, VT1
Input Termination Center-Tap: Each side of the differential input pair terminates to a VT
VT2, VT3
pin. The VT pin provides a center-tap to the termination network for maximum
interface flexibility. See “Input Interface Applications” section for more details.
15, 18
SEL0, SEL1
This single-ended TTL/CMOS compatible input selects the inputs to the multiplexer. Note
that this input is internally connected to a 25k pull-up resistor and will default to a logic
HIGH state if left open. Input logic threshold is VCC/2. See “Truth Table” for select control.
14, 19
NC
No Connect.
10, 13, 16
VCC
Positive Power Supply: Bypass with 0.1F0.01F low ESR capacitors.
17, 20, 23
11, 12
/Q0, Q0
Differential Outputs: These CML output pairs are copies of the selected input. Unused
21, 22
/Q1, Q1
output pairs may be left floating. See “Output Interface” section for termination guidelines.
9, 24
GND,
Ground. Ground pin and exposed pad must be connected to the same ground plane.
Exposed Pad
3, 7, 27, 31
VREF-AC0
Reference Voltage: This reference output is equivalent to VCC–1.4V. It is used for AC-coupled
VREF-AC1
inputs. When interfacing to AC input signals, connect VREF-AC directly to the VT pin and
VREF-AC2
bypass with 0.01F low ESR capacitor to VCC. See “Input Interface Applications” section.
VREF-AC3
Maximum sink/source current is 0.5mA.
