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
