SN74LVC1G373DCKR屬于集成電路（IC）的鎖存器。由美國(guó)德州儀器公司制造生產(chǎn)的SN74LVC1G373DCKR鎖存器鎖存器是類(lèi)似于觸發(fā)器的基本數(shù)字存儲(chǔ)設(shè)備，但是不同之處在于，在鎖存使能（或類(lèi)似命名）信號(hào)處于有效邏輯狀態(tài)的任何時(shí)間，保持的邏輯狀態(tài)都可以改變。“透明”鎖存器還允許設(shè)備輸出在鎖存使能信號(hào)有效時(shí)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(shí)改變。

3 Description

The SN74LVC1G373 device is a single D-type latch

designed for 1.65-V to 5.5-V VCC operation.

This device is particularly suitable for implementing

buffer registers, I/O ports, bidirectional bus drivers,

and working registers. 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 logic levels set up at the D inputs.

NanoFree? package technology is a major

breakthrough in IC packaging concepts, using the die

as the package.

OE does not affect the internal operations of the

latch. Old data can be retained or new data can be

entered while the outputs are in the high-impedance

state.
