74ACT16861DLR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74ACT16861DLR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(fù)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(jìn)行隔離通信。

description

The ’ACT16861 are noninverting 20-bit

transceivers designed for asynchronous

communication between data buses. The

control-function implementation minimizes

external timing requirements.

The ’ACT16861 can be used as two 10-bit

transceivers or one 20-bit transceiver. They allow

data transmission from the A bus to the B bus or

from the B bus to the A bus, depending upon the

logic level at the output-enable (OEAB or OEBA)

inputs. The output-enable inputs can be used to

disable the device so that the buses are effectively

isolated.

The 74ACT16861 is packaged in TI’s shrink small-outline package, which provides twice the I/O pin count and

functionality of standard small-outline packages in the same printed-circuit-board area.

The 54ACT16861 is characterized for operation over the full military temperature range of –55°C to 125°C. The

74ACT16861 is characterized for operation from –40°C to 85°C.
