MC54/74HC154 is a 16 channel integrated circuit for memory address decoding and data routing
The MC54/74HC154 is a 1‑of‑16 decoder/demultiplexer CMOS device that selects one of sixteen active‑low outputs. It is pin‑compatible with the LS154 and is commonly used for memory address decoding and data routing applications. The device operates with standard CMOS inputs and can interface directly to CMOS, NMOS, and TTL logic families.
Key specifications include an operating voltage range of 2 V to 6 V, output drive capability of 10 LSTTL loads, low input current of 1 pA, and power dissipation up to 750 mW (plastic DIP). The part is offered in ceramic (CASE 758‑02), plastic (CASE 724‑03), and SOIC (CASE 751E‑04) packages, with detailed pin assignments and timing characteristics provided in the data sheet.
