IN0, /IN0,
IN1, /IN1
Differential Inputs: These input pairs are the differential signal inputs to the
device. These inputs accept AC- or DC-coupled signals as small as 100mV
(200mVpp). Each pin of a pair internally terminates to a VT pin through 50
.
Please refer to the “Input Interface Applications” section for more details.
2, 14
VREF-AC0
VREF-AC1
Reference Voltage: These outputs bias to VCC –1.2V. They are used for AC-
coupling inputs IN and /IN. Connect VREF-AC directly to the corresponding VT
pin. Bypass with 0.01F low ESR capacitor to VCC. Maximum sink/source
current is ±1.5mA.
3, 15
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 the “Input Interface Applications” section
for more details.
5, 8, 12
VCC
Positive Power Supply: Bypass with 0.1F||0.01F low ESR capacitors as close
to the VCC pins as possible.
6, 7
Q, /Q
Differential Outputs: This differential CML output is a logic function of the IN0,
IN1, and SEL inputs. Please refer to the “Truth Table” below for details.
10
SEL
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 logic HIGH state if left open.
9
GND,
Exposed Pad
Ground: Ground and exposed pad must be connected to the same ground plane.
11
CAP
Power-On Reset (POR) initialization capacitor. When using the multiplexer with
RPE capability, this pin is tied to a capacitor to VCC. The purpose is to ensure
the internal RPE logic starts up in a known state. See “Power-On Reset (POR)
Description” section for more details regarding capacitor selection. If this pin is
tied directly to VCC, the RPE function will be disabled and the multiplexer will
function as a normal multiplexer. The CAP pin should never be left open.
