Description
The 74LCX157 is a low voltage CMOS Quad 2 channel multiplexer fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power and high speed 3.3V applications; it can be interfaced to 5V signal environment for inputs.
   
Features
■ 5V tolerant inputs
■ High speed:
    – tPD = 6.0ns (Max) at VCC = 3V
■ Power down protection on inputs and outputs
■ Symmetrical output impedance:
    – |IOH| = IOL = 24mA (Min) at VCC = 3V
■ PCI bus levels guaranteed at 24mA
■ Balanced propagation delays: – tPLH ≅ tPHL
■ Operating voltage range:
    – VCC (Opr) = 2.0V to 3.6V
■ Pin and function compatible with
    74 series 157
■ Latch-up performance exceeds
    500mA (JESD 17)
■ ESD performance:
    – HBM > 2000V
        (MIL STD 883 method 3015); MM > 200V
