74LVQ157
Low Voltage Quad 2-Input Multiplexer
General Description
The LVQ157 is a high-speed quad 2-input multiplexer. Four
bits of data from two sources can be selected using the
common Select and Enable inputs. The four outputs
present the selected data in the true (non inverted) form.
The LVQ157 can also be used as a function generator.
Features
s Ideal for low power/low noise 3.3V applications
s Guaranteed simultaneous switching noise level and
dynamic threshold performance
s Guaranteed pin-to-pin skew AC performance
s Guaranteed incident wave switching into 75Ω.
