74HC(T)259: 8位可寻址锁存器
74HC259；74HCT259是高速硅栅CMOS器件并且与低功耗肖特基TTL（LSTTL）引脚兼容。它们符合JEDEC标准No. 7A。
74HC259；74HCT259是高速8位可寻址锁存器，设计用于数字系统的通用存储应用。它们是多功能器件，能够将单线路数据存储在八个可寻址锁存器中。它们提供带有源高电平输出（Q0至Q7）的3到8线路解码器和多路复用器功能。它们还包括一个可复位所有锁存器的有源低电平通用复位（MR）以及一个有源低电平使能输入（LE）。
74HC259；74HCT259具有四种操作模式：
运行74HC259时；74HCT259作为更改多个地址位的地址锁存器，可实行一个瞬态错误地址。因此，这仅能在存储器模式下实行。
