描述 Description

General Description
The SCAN182245A is a high performance BiCMOS bidirectional line driver featuring separate data inputs organized into dual 9-bit bytes with byte-oriented output enable and direction control signals. This device is compliant with IEEE 1149.1 Standard Test Access Port and Boundary Scan Architecture with the incorporation of the defined boundary-scan test logic and test access port consisting of Test Data Input (TDI), Test Data Out (TDO), Test Mode Select (TMS), and Test Clock (TCK).

特性 Features

■ High performance BiCMOS technology
■ 25? series resistors in outputs eliminate the need for
?? external terminating resistors
■ Dual output enable control signals
■ 3-STATE outputs for bus-oriented applications
■ 25 mil pitch SSOP (Shrink Small Outline Package)
■ IEEE 1149.1 (JTAG) Compliant
■ Includes CLAMP, IDCODE and HIGHZ instructions
■ Additional instructions SAMPLE-IN, SAMPLE-OUT and
?? EXTEST-OUT
■ Power Up 3-STATE for hot insert
■ Member of Fairchild’s SCAN Products

簡(jiǎn)介

SCAN182245A屬于集成電路（IC）的緩沖器驅(qū)動(dòng)器接收器收發(fā)器。由制造生產(chǎn)的SCAN182245A緩沖器，驅(qū)動(dòng)器，接收器，收發(fā)器邏輯緩沖器、驅(qū)動(dòng)器、接收器和收發(fā)器允許隔離對(duì)某個(gè)電路的邏輯信號(hào)的訪(fǎng)問(wèn)，以用于另一電路。緩沖器將其輸入信號(hào)（不變或反相）傳遞到其輸出，并可能用于清除弱信號(hào)或驅(qū)動(dòng)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(xiàn)之間進(jìn)行隔離通信。
