74LVQ157 Low Voltage Quad 2-Input Multiplexer February 1992 Revised June 2001 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 75.
