MC74LCX16373集成電路（IC）的鎖存器規(guī)格書PDF中文資料

MC74LCX16373屬于集成電路（IC）的鎖存器。由安森美半導體公司制造生產的MC74LCX16373鎖存器鎖存器是類似于觸發(fā)器的基本數(shù)字存儲設備，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。“透明”鎖存器還允許設備輸出在鎖存使能信號有效時反映輸入的當前狀態(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 16?Bit Transparent Latch

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

The MC74LCX16373 is a high performance, non?inverting 16?bit transparent latch operating from a 2.3 V to 3.6 V supply. The device is byte controlled. Each byte has separate Output Enable and Latch Enable inputs. These control pins can be tied together for full 16?bit operation. 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 MC74LCX16373 inputs to be safely driven from 5.0 V devices.
