The NB7L86A 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 3x3 mm 16 pin QFN package.Differential inputs incorporate internal 50-ohm termination resistors and accept NECL (Negative ECL), PECL (Positive ECL), LVCMOS/LVTTL, CML, or LVDS. The OLS input is used to program the peak-to-peak output amplitude between 0 and 800 mV in five discrete steps.The NB7L86A employs input default circuitry so that under open input condition, the outputs of the device remain stable.
