MC100E457

MC10E457, MC100E457 5 V ECL Triple Differential 2:1 Multiplexer Description The MC10E457/100E457 is a 3-bit differential 2:1 multiplexer. The fully differential data path makes the device ideal for multiplexing low skew clock or other skew sensitive signals. The higher frequency outputs provide the device with a > 1.0 GHz bandwidth to meet the needs of the most demanding system clock. Both, separate selects and a common select, are provided to make the device well suited for both data path and random logic applications. The differential inputs have internal clamp structures which will force the Q output of a gate in an open input condition to go to a LOW state. Thus, inputs of unused gates can be left open and will not affect the operation of the rest of the device. Note that the input clamp will take affect only if both inputs fall 2.5 V below VCC. The 100 Series contains temperature compensation. Multiple VBB pins are provided to ease AC coupling input signals. The VBB pins, interna...
