DS36954屬于集成電路（IC）的驅(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DS36954驅(qū)動器，接收器，收發(fā)器該系列產(chǎn)品的主要功能是提供必需的硬件資源，以通過延長電纜或印制線進(jìn)行通信。確切的功能會因所采用的通信協(xié)議而異，可能包括諸如瞬態(tài)抑制之類的功能，這些功能對于通信用途可能并非絕對必要，但對于可能的使用環(huán)境卻是明智之選。

DESCRIPTION

The DS36954 is a low power, quad EIA-485

differential bus transceiver especially suited for high

speed, parallel, multipoint, I/O bus applications. A

compact 20-pin surface mount PLCC or SOIC

package provides high transceiver integration and a

very small PC board footprint.

Propagation delay skew between devices is specified

to aid in parallel interface designs—limits on

maximum and minimum delay times are verified.

Five devices can implement a complete SCSI initiator

or target interface. Three transceivers in a package

are pinned out for data bus connections. The fourth

transceiver, with the flexibility provided by its

individual enables, can serve as a control bus

transceiver.
