The MC74LVX138MELG is a high-speed CMOS 3-to-8 line decoder from Quarktwin Technology Ltd. It features 5V-tolerant inputs, allowing compatibility between 5.0 V and 3.0 V systems. The device operates with a typical propagation delay of 5.5 ns at a supply voltage of 3.3 V and has a maximum power dissipation of 4 ¬µA at 25 ¬8C, making it suitable for low-power applications. The decoder includes three binary select inputs (A0, A1, A2) and three enable inputs (E1, E2, E3), which facilitate cascading and memory addressing. When enabled, one of the eight outputs (O0 to O7) will go low based on the binary input combination. If the enable inputs are not properly set, all outputs will remain high. The device also boasts balanced propagation delays and low noise characteristics, with a maximum output low voltage of 0.5 V. The MC74LVX138MELG is available in a 16-lead SOEIAJ package and is compliant with Pb-free standards, making it suitable for environmentally conscious designs. Its latchup performance exceeds 300 mA, and it offers robust ESD protection, with ratings of over 2000 V for the human body model and over 200 V for the machine model.
