74HCT154PW,118 4-to-16 Line Decoder/Demultiplexer | High-Speed CMOS | TSSOP-24 SMD

Description

The 74HCT154PW,118 is a high-speed 4-to-16 line decoder/demultiplexer. This device accepts four binary-weighted address inputs (A0–A3) and, when enabled, provides 16 mutually exclusive active-LOW outputs. It features two active-LOW enable inputs (E1 and E2), which are designed to simplify cascading or expansion for larger decoder configurations.

As a member of the HCT series, the 74HCT154 is engineered to be TTL-compatible, allowing it to interface directly with standard 5V TTL logic while providing the low power consumption and high noise immunity of CMOS technology. This makes it a highly versatile component for memory address decoding, data routing, and complex digital signal distribution. The TSSOP-24 surface-mount package is optimized for space-efficient, high-density PCB layouts, making it ideal for compact electronic assemblies.
