SCAN182245A集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF中文资料

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).

Features
