SN74LVTH16373GRDR屬于集成電路（IC）的鎖存器。由美國德州儀器公司制造生產(chǎn)的SN74LVTH16373GRDR鎖存器鎖存器是類似于觸發(fā)器的基本數(shù)字存儲(chǔ)設(shè)備，但是不同之處在于，在鎖存使能（或類似命名）信號(hào)處于有效邏輯狀態(tài)的任何時(shí)間，保持的邏輯狀態(tài)都可以改變。“透明”鎖存器還允許設(shè)備輸出在鎖存使能信號(hào)有效時(shí)反映輸入的當(dāng)前狀態(tài)，而相反的是，狀態(tài)僅在保持狀態(tài)已固定時(shí)改變。

DESCRIPTION/ORDERING INFORMATION

The 'LVTH16373 devices are 16-bit transparent D-type latches with 3-state outputs designed for low-voltage

(3.3-V) VCC operation, but with the capability to provide a TTL interface to a 5-V system environment. These

devices are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and

working registers.
