Product Overview

The 74HC138N is a 3-to-8 line Decoder or Demultiplexer with inverting and decodes three binary weighted address inputs to eight mutually exclusive outputs. The device features three enable inputs. Every output will be high unless E1 and E2 are low and E3 is high. This multiple enable function allows easy parallel expansion to a 1-of-32 (5 to 32 lines) decoder with just four 138 ICs and one inverter. The 138 can be used as an eight output demultiplexer by using one of the active low enable inputs as the data input and the remaining enable inputs as strobes. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
  • CMOS input level
  • Demultiplexing capability
