SN74ABT162841DGGR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SN74ABT162841DGGR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

These 20-bit transparent D-type latches feature

noninverting 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 ’ABT162841 devices can be used as two

10-bit latches or one 20-bit latch. While the

latch-enable (1LE or 2LE) input is high, the Q

outputs of the corresponding 10-bit latch follow

the data (D) inputs. When LE is taken low, the

Q outputs are latched at the levels set up at the D

inputs.
