Differential Inputs: These input pairs are the differential signal inputs to the device. Inputs
accept AC- or DC-coupled signals as small as 100mV. Each pin of a pair internally
terminates to a VT pin through 50
. Note that these inputs will default to an indeterminate
state if left open. Connecting one input to VCC and the complementary input-to-GND
through 1k
resistor can terminate unused differential input pairs. The VT pin is to be left
open in this configuration. Please refer to the “Input Interface Applications” section for more
details.
10, 13, 16, 17,
20, 23
VCC
Positive power supply. Bypass with 0.1F//0.01F low ESR capacitors. The 0.01F
capacitor should be as close to VCC pin as possible.
14, 19
NC
Not connected.

SELA,
SELB
Bank A and Bank B Input Channel Select (TTL/CMOS): These TTL/CMOS-compatible
inputs select the inputs to the multiplexers. These inputs are internally connected to a
25k
pull-up resistor and will default to logic HIGH state if left open.

Differential Outputs: These LVPECL output pairs are the outputs of the device. They are a
logic function of the INA0, INA1, INB0, INB1 and SELA and SELB inputs. Please refer to
the “Truth Table” below for details.

Input Termination Center-Tap: Each side of the differential input pair terminates to a VT
pin. The VTA0, VTA1, VTB0, VTB1 pins provide a center-tap to a termination network for
maximum interface flexibility. See “Input Interface Applications” section for details.

VREF-ACA0,
VREF-ACA1,
VREF-ACB0,
VREF-ACB1
Reference Voltages: These reference voltage outputs are equivalent to VCC-1.2V. They are
used for AC-coupled inputs. Connect VREF-AC directly to the VT pin and bypass with
0.01
F low ESR capacitor to VCC. See “Input Interface Applications” section. Maximum
sink/source current is
±1.5mA.

Exposed Pad
Ground: Ground pins and exposed pad must be connected to the same ground plane.
