The HD74ALVCH16825 is an 18-bit buffer/driver with 3-state outputs. It provides true data and features high output current and high voltage tolerance.
The HD74ALVCH16825 is an 18‑bit buffer/driver that can be configured as two 9‑bit buffers or a single 18‑bit buffer. It features true 3‑state outputs, bus‑hold circuitry, and high output current capability, making it suitable for memory address drivers, clock drivers, and bus‑oriented receivers and transmitters.
Key specifications include a supply voltage range of 2.3 V–3.6 V, up to 24 mA output current, propagation delays as low as 2.5 ns, and a 56‑lead TSSOP package measuring 14 mm × 33 mm. The document also lists absolute maximum ratings, recommended operating conditions, pin assignments, and typical waveforms.
