74AHC573BQ: 八进制D型透明锁存器;3态

74AHC573;74AHCT573是高速硅栅CMOS器件,与低功耗肖特基TTL (LSTTL)针脚兼容。该类器件的规格符合JEDEC标准No. 7A。

74AHC573;74AHCT573 由八个D型穿透锁存器组成,具有适用于每个锁存器的单独D型输入和适合总线应用的3态真正输出。锁存使能输入(LE)和输出使能输入(OE)为所有锁存器共用。

针脚LE为高电平时,Dn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,即每当与锁存输出对应的Dn输入发生变化时,锁存输出就会随之发生改变。针脚LE为低电平时,锁存器存储LE从高电平跃迁至低电平前的一个设置时间在Dn输入处出现的信息。

针脚OE为低电平时,8个锁存器的内容可在输出处获取。针脚OE为高电平时,输出转为高阻抗关断状态。OE输入的操作不会影响锁存器的状态。

74AHC573;74AHCT573在功能上等同于74AHC373;74AHCT373,但针脚排列不同。
