SN74LVC841ADW屬于集成電路（IC）的鎖存器。由美國德州儀器公司制造生產(chǎn)的SN74LVC841ADW鎖存器鎖存器是類似于觸發(fā)器的基本數(shù)字存儲設(shè)備，但是不同之處在于，在鎖存使能（或類似命名）信號處于有效邏輯狀態(tài)的任何時間，保持的邏輯狀態(tài)都可以改變?！巴该鳌辨i存器還允許設(shè)備輸出在鎖存使能信號有效時反映輸入的當(dāng)前狀態(tài)，而相反的是，狀態(tài)僅在保持狀態(tài)已固定時改變。

DESCRIPTION/ORDERING INFORMATION

This 10-bit bus-interface D-type latch is designed for 1.65-V to 3.6-V VCC operation.

The SN74LVC841A is designed specifically for driving highly capacitive or relatively low-impedance loads. It is

particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

The ten latches are transparent D-type latches. The device has noninverting data (D) inputs and provides true

data at its outputs.

A buffered output-enable (OE) input can be used to place 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.
