74LVX157

74LVX157 Low Voltage Quad 2-Input Multiplexer May 1993 Revised March 1999 74LVX157 Low Voltage Quad 2-Input Multiplexer General Description The LVX157 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 (noninverted) form. The LVX157 can also be used as a function generator. Features s Input voltage level translation from 5V to 3V s Ideal for low power/low noise 3.3V applications s Guaranteed simultaneous switching noise level and dynamic threshold performance Ordering Code: Order Number 74LVX157M 74LVX157SJ 74LVX157MTC Package Number M16A M16D MTC16 Package Description 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150” Narrow 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 16-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Devices are also available in Tape and Reel.
