Part Details:

74LCX257 May 1995 Revised September 2000 Low V 74LCX257Low Voltage Quad 2-Input Multiplexer olt with 5V Tolerant Inputs and Outputs age General Description Features Quad 2- The LCX257 is a quad 2-input multiplexer with 3-STATE s 5V tolerant inputs and outputs outputs. Four bits of data from two sources can be selected s 2.3V­3.6V VCC specifications provided using a Common Data Select input. The four outputs s present the selected data in true (non inverted) form. The 6.0 ns tPD max (VCC = 3.3V, In Zn), 10 µA ICC max outputs may be switched to a high impedance state by s Power down high impedance inputs and outputs Input placing a logic HIGH on the common Output Enable (OE) s Supports live insertion/withdrawal (Note 1) input, allowing the outputs to interface directly with bus-ori- s Implements patented noise/EMI reduction circuitry ented systems. Mul s Latch-up performance exceeds 500 mA The 74LCX257 is fabricated with advanced CMOS technol-ogy to achieve high speed operation while maintaining s ESD performance: t CMOS low power dissipation. Human body model > 2000V iplex Machine model > 200V Note 1: To ensure the high-impedance state during power up or down, OE e should be tied to VCC through a pull-up resistor: the minimum value or the r w resistor is determined by the current-sourcing capability of the driver. ith 5V T Ordering Code: Order Number Package Number Package Description o 74LCX257M M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow lera 74LCX257SJ M16D 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide
