MC74LVX138
3−to−8 Line Decoder
With 5V−Tolerant Inputs
The MC74LVX138 is an advanced high speed CMOS 3−to−8 line
decoder. The inputs tolerate voltages up to 7.0 V, allowing the
interface of 5.0 V systems to 3.0 V systems.
When the device is enabled, three Binary Select inputs (A0 − A2)
determine which one of the outputs (O0 − O7) will go Low. When
enable input E3 is held Low or either E2 or E1 is held High, decoding
function is inhibited and all outputs go high. E3, E2, and E1 inputs are
provided to ease cascade connection and for use as an address decoder
for memory systems.
Features
• High Speed: tPD = 5.5 ns (Typ) at VCC = 3.3 V
• Low Power Dissipation: ICC = 4 mA (Max) at TA = 25 °C
• Power Down Protection Provided on Inputs
• Balanced Propagation Delays
• Low Noise: VOLP = 0.5 V (Max)
• Pin and Function Compatible with Other Standard Logic Families
• Latchup Performance Exceeds 300 mA
• ESD Performance:

Average operating current can be obtained by the equation: ICC(OPR) = CPD VCC fin + ICC . CPD is used to determine the no−load dynamic
power consumption; PD = CPD VCC2 fin + ICC VCC.
