74ALVCH32973EC: 16位总线收发器和D型透明锁存器,具有8个独立的缓冲区

74ALVCH32973是16位总线收发器和D型透明锁存器,具有8个带总线保持输入和3态输出的独立缓冲器。其具有方向(1DIR,2DIR)输入、锁存使能(1LOE,2LOE)输入、收发器输出使能(1TOE,2TOE)输入和锁存使能(1LE,2LE)控制输入;四个8位收发器端口(1An,2An和1Bn,2Bn);两个8位D型锁存输出端口(1Qn,2Qn)和一个带数据输入Dn和输出Yn的8位缓冲器。控制针脚的配置允许该器件用作一个8位缓冲器、两个8位收发器和两个8位锁存器或一个8位缓冲器、一个16位收发器和一个16位锁存器。

8位缓冲器工作时独立于控制输入。A和B之间的数据传输方向由nDIR控制,当nTOE置于高电平时,A和B端口将呈高阻抗关断状态,因此能得到有效隔离。nLE为高电平时,A输入处的数据会输入锁存器。在这种情况下,锁存器是穿透的,每当与Q输出对应的A输入发生变化时,Q输出就会随之变化。nLE为低电平时,锁存器会存储nLE从高电平跃迁至低电平前的一个设置时间在输入处出现的信息。nLOE上的高电平使Q输出呈高阻抗关断状态。nLOE输入的操作不会影响锁存器的状态。
