SN74CBT3345中文資料5V、1:1 (SPST)、8 通道 FET 總線開關(guān)數(shù)據(jù)手冊TI規(guī)格書

描述 Description

The SN74CBT3345 provides eight bits of high-speed TTL-compatible bus switching in a standard ?245 device pinout. The low on-state resistance of the switch allows connections to be made with minimal propagation delay.

The device is organized as one 8-bit switch bank with dual output-enable (OE and OE)\\ inputs. When OE\\ is low or OE is high, the switch is on, and port A is connected to port B. When OE\\ is high and OE is low, the switch is open, and the high-impedance state exists between the two ports.

簡介

SN74CBT3345屬于集成電路（IC）的信號開關(guān)多路復(fù)用器解碼器。由TI制造生產(chǎn)的SN74CBT3345信號開關(guān)，多路復(fù)用器，解碼器邏輯型信號開關(guān)、多路復(fù)用器和編碼器 IC 可用于對以數(shù)字格式表示數(shù)據(jù)的電信號進(jìn)行路由和選擇。這些器件與設(shè)計用于模擬信號的類似產(chǎn)品有所不同，它們保留的信息表示為兩個電狀態(tài)之一，而不是兩個外部界限內(nèi)的無窮變化量。
