Overview

MC74AC273/74ACT273 は、8 つのエッジトリガ D タイプ・フリップフロップに、 個別の D 入力および Q 出力が付いています。共通のバッファされたクロック (CP) とマスター・ リセット (MR) 入力は、すべてのフリップフロップに同時に負荷をかけて、リセット (クリア) します。このレジスタは完全エッジトリガされます。各 D 入力のステート (LOW から HIGH クロックへの遷移前 の 1 つの設定時間) は、関連するフリップ フロップの Q 出力へ送られます。出力はすべて、クロックまたはデータ入力に関係なく、MR 入力の電圧レベルが LOW になると、強制的に LOW にされます。このデバイスは、トゥルー 出力だけ求められるアプリケーションに有用で、クロックおよびマスター・リセットはすべての 記憶素子に共通です。
