SN74ALS541DBR集成電路（IC）的緩沖器驅動器接收器收發(fā)器規(guī)格書PDF中文資料

SN74ALS541DBR屬于集成電路（IC）的緩沖器驅動器接收器收發(fā)器。由德州儀器制造生產的SN74ALS541DBR緩沖器，驅動器，接收器，收發(fā)器邏輯緩沖器、驅動器、接收器和收發(fā)器允許隔離對某個電路的邏輯信號的訪問，以用于另一電路。緩沖器將其輸入信號（不變或反相）傳遞到其輸出，并可能用于清除弱信號或驅動負載。在布爾邏輯仿真器中，緩沖器主要用于增加傳播延遲。邏輯接收器和收發(fā)器允許在數(shù)據(jù)總線之間進行隔離通信。

description

These octal buffers and line drivers are designed

to have the performance of the popular

SN54ALS240A/SN74ALS240A series and, at

the same time, offer a pinout with inputs and

outputs on opposite sides of the package. This

arrangement greatly facilitates printed circuit

board layout.

The 3-state control gate is a 2-input NOR gate

such that, if either output-enable (OE1 or OE2)

input is high, all eight outputs are in the

high-impedance state.

The SN74ALS540 provides inverted data. The

’ALS541 provide true data at the outputs.

The -1 versions of SN74ALS540 and

SN74ALS541 are identical to the standard

versions, except that the recommended

maximum IOL is increased to 48 mA. There is no

-1 version of the SN54ALS541.
