Product Overview
The CY74FCT841CTQC from Texas Instruments is a high-performance 10-bit D-type latch designed for bus-oriented applications. It features 3-state outputs, making it ideal for driving high-capacitance loads while maintaining signal integrity. Operating from a 5V supply, this device offers a balanced combination of speed and power efficiency, with a typical propagation delay of 6.5 ns and a maximum quiescent current of 500 µA. The latch is transparent when the latch enable (LE) input is high, and stores data when LE is low. The output enable (OE) control allows the outputs to be placed in a high-impedance state for bus sharing.

產品概述
CY74FCT841CTQC 是德州儀器推出的一款高性能 10 位 D 型鎖存器,專為匯流排應用設計。它具備三態輸出,能夠在驅動高電容負載的同時保持信號完整性。該器件工作在 5V 電源下,典型傳播延遲為 6.5 ns,最大靜態電流為 500 µA,在速度和功耗之間實現了良好平衡。當鎖存使能 (LE) 輸入為高電平時,鎖存器透明傳輸數據;LE 為低電平時則存儲數據。輸出使能 (OE) 控制可將輸出置為高阻抗狀態,便於匯流排共享。
