NBSG86A
2.5V/3.3V SiGe Differential
Smart Gate with Output
Level Select
The NBSG86A is a multi-function differential Logic Gate which
can be configured as an AND/NAND, OR/NOR, XOR/XNOR, or 2:1
MUX. This device is part of the GigaComm™ family of high
performance Silicon Germanium products. The device is housed in a
low profile 4x4 mm, 16-pin, flip-chip LGA or a 3x3 mm 16 pin QFN
package.
Differential inputs incorporate internal 50
W
termination resistors
and accept NECL (Negative ECL), PECL (Positive ECL),
LVCMOS/LVTTL, CML, or LVDS. The Output Level Select (OLS)
input is used to program the peak- to- peak output amplitude between
0 and 800 mV in five discrete steps.
The NBSG86A employs input default circuitry so that under open
input conditions (D
x
, D
x
, VTD
x
, VTD
x,
VTSEL) the outputs of the
device will remain stable.

1. In the differential configuration when the input termination pins (VTDx, VTDx, VTSEL) are connected to a common termination voltage,
and if no signal is applied then the device will be susceptible to self-oscillation.
2. All V

pins must be externally connected to Power Supply to guarantee proper operation.
3. When an output level of 400 mV is desired and V
