3 to 8 Line Decoder
MM74HC138 3-to-8 Line Decoder September 1983 Revised February 1999 MM74HC138 3-to-8 Line Decoder The decoder’s outputs can drive 10 low power Schottky General Description TTL equivalent loads, and are functionally and pin equiva- The MM74HC138 decoder utilizes advanced silicon-gate lent to the 74LS138. All inputs are protected from damage CMOS technology and is well suited to memory address due to static discharge by diodes to V and ground. CC decoding or data routing applications. The circuit features high noise immunity and low power consumption usually Features associated with CMOS circuitry, yet has speeds compara- ble to low power Schottky TTL logic. � Typical propagation delay: 20 ns The MM74HC138 has 3 binary select inputs (A, B, and C). � Wide power supply range: 2V–6V If the device is enabled, these inputs determine which one � Low quiescent current: 80 μA maximum (74HC Series) of the eight normally HIGH outputs will go LOW. Two active � Low input current: 1 μA maximum LOW and one active HIGH enables (G1, G2A and G2B) � Fanout of 10 LS-TTL loads are provided to ease the cascading of decoders.
