SN74BCT543DW屬于集成電路（IC）的緩沖器驅(qū)動器接收器收發(fā)器。由美國德州儀器公司制造生產(chǎn)的SN74BCT543DW緩沖器，驅(qū)動器，接收器，收發(fā)器邏輯緩沖器、驅(qū)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(qū)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

The ′BCT543 octal transceiver contains two sets

of D-type latches for temporary storage of data

flowing in either direction. Separate latch-enable

(LEAB or LEBA) and output-enable (OEAB or

OEBA) inputs are provided for each register to

permit independent control in either direction of

data flow.

The A-to-B enable (CEAB) input must be low in

order to enter data from A or to output data from

B. If CEAB is low and LEAB is low, the A-to-B

latches are transparent; a subsequent low-to-high

transition of LEAB puts the A latches in the storage

mode. With CEAB and OEAB both low, the 3-state

B outputs are active and reflect the data present

at the output of the A latches. Data flow from B to

A is similar but requires using the CEBA, LEBA,

and OEBA inputs.

The SN54BCT543 is characterized for operation

over the full military temperature range of ?55°C

to 125°C. The SN74BCT543 is characterized for

operation from 0°C to 70°C.
