Product Description

The device accepts a three-bit binary weighted address on input pins A0, A1, and A2 and, when enabled, provides eight mutually exclusive active-LOW outputs (Y0 to Y7). The device features three enable inputs: two active-LOW (E1 and E2) and one active-HIGH (E3). The demultiplexer is enabled when E1 and E2 are held low and E3 is held high. This configuration ensures the device is versatile for various logic operations and can be integrated into a multitude of complex circuits.

With its wide operating temperature range and protection against static discharge and power-down issues, the 74HCT138N,652 is a reliable choice for critical and demanding applications. The DIP-16 (Dual In-line Package) makes it suitable for through-hole mounting, which is advantageous for prototyping and educational purposes.
