74LVC573A集成電路（IC）的鎖存器規(guī)格書PDF中文資料

74LVC573A屬于集成電路（IC）的鎖存器。由安森美半導(dǎo)體公司制造生產(chǎn)的74LVC573A鎖存器鎖存器是類似于觸發(fā)器的基本數(shù)字存儲設(shè)備，但是不同之處在于，在鎖存使能（或類似命名）信號處于有效邏輯狀態(tài)的任何時間，保持的邏輯狀態(tài)都可以改變?！巴该鳌辨i存器還允許設(shè)備輸出在鎖存使能信號有效時反映輸入的當(dāng)前狀態(tài)，而相反的是，狀態(tài)僅在保持狀態(tài)已固定時改變。

Low-Voltage CMOS Octal Transparent Latch

With 5 V?Tolerant Inputs and Outputs (3?State, Non?Inverting)

The 74LVC573A is a high performance, non?inverting octal transparent latch operating from a 1.2 to 3.6 V supply. High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. A VI specification of 5.5 V allows 74LVC573A inputs to be safely driven from 5 V devices.
