The 54AC378 is a 6-bit parallel D register with a buffered common Enable.
The 54AC/74AC378 is a 6‑bit parallel D‑type register featuring positive‑edge‑triggered inputs and a fully buffered common clock and enable. It is designed for high‑speed applications and includes input clamp diodes to limit termination effects.
Key features include a supply voltage range of –0.5 V to +7.0 V, operating temperature from –40 °C to +85 °C (commercial grade), maximum output current of ±20 mA, and typical propagation delays of a few nanoseconds. The device is offered in multiple package styles such as DIP, SOIC, Flatpak, and LCC.
