Description
The 74LCX138 is a low voltage CMOS 3 to 8 line decoder (inverting) 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 = 6.7ns (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 138
■ Latch-up performance exceeds 500mA (JESD 17)
■ ESD performance:
– HBM > 2000V
(MIL STD 883 method 3015); MM > 200V
