SN74ALS841 具有三态输出的 10 位总线接口 D 类锁存器

These 10-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 ten latches are transparent D-type latches. The SN74ALS841 and SN74AS841A have noninverting data (D) inputs. The SN74ALS842 has inverting D\ inputs.

A buffered output-enable () input places the ten outputs in either a normal logic state (high or low logic levels) or a high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and increased drive provide the capability to drive bus lines without interface or pullup components.
