Product Description

The device features three binary select inputs (A, B, and C), which determine which one of the eight outputs (Y0 to Y7) will go low when the enable input (E) is held at a logical low level. This enables the use of this chip as a demultiplexer by using the select inputs as data input and the E input as the data enable signal. The 74HC138PW,118 also includes two active-low enable inputs (E1 and E2) and one active-high enable input (E3), which must be in the correct logical state for the device to operate.

Constructed in a TSSOP package, the 74HC138PW,118 is designed for space-saving on PCBs, making it an excellent choice for compact designs. It is also characterized by low power consumption and high noise immunity, typical of CMOS integrated circuits, ensuring stable operation in various environmental conditions.
