TC74HC138AP — 3-to-8 decode & active-LOW outputs

TC74HC138AP selects one of eight outputs based on three address inputs A, B, and C. Outputs are active-LOW, and three enables (G1 HIGH, G2A/G2B LOW) simplify cascading and demultiplexing. The device runs on 2–6 V rails, offers HC-class speed (≈tens of ns), and maintains low CMOS power. Through-hole DIP-16 packaging makes TC74HC138AP ideal for prototyping, education, and service work. Use TC74HC138AP to route chip-selects, generate one-hot lines, or decode addresses cleanly on 3.3 V and 5 V systems. Need TC74HC138AP with compliant paperwork and fast U.S. shipping?
