SN74LVCR16245ADGVR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SN74LVCR16245ADGVR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。

3 Description

This 16-bit (dual-octal) noninverting bus transceiver is

designed for 1.65-V to 3.6-V VCC operation.

The SN74LVCR16245A device is designed for

asynchronous communication between data buses.

All inputs and outputs have equivalent 26-Ω resistors

that will slow the edges of the output and reduce

switching noise caused by long capacitive etch runs

or cables.

This device can be used as two 8-bit transceivers or

one 16-bit transceiver. Active bus-hold circuitry holds

unused or undriven data inputs at a valid logic state.
