SN74HC373PWR Description
These 8-bit latches feature 3-state outputs designed
specifically for driving highly capacitive or relatively
low-impedance loads. They are particularly suitable
for implementing buffer registers, I/O ports,
bidirectional bus drivers, and working registers.
The eight latches of the ’HC373 devices are
transparent D-type latches. While the latch-enable
(LE) input is high, the Q outputs follow the data (D)
inputs. When LE is taken low, the Q outputs are
latched at the levels that were set up at the D inputs.(描述这些8位锁存器采用了专为驱动高电容或相对低阻抗负载而设计的三态输出。它们特别适用于实现缓冲寄存器、I/O端口、双向总线驱动器和工作寄存器。HC373设备的8个锁存器是透明的D型锁存器。虽然锁存使能（LE）输入为高电平，Q输出跟随数据（D）输入。当LE是采取低，Q输出锁存的水平是在D输入成立。)
