74ACT16245数据手册集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF

描述 Description

The SN54ACT16245 and 74ACT16245 are 16-bit bus transceivers organized as dual-octal noninverting 3-state transceivers and designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements.
The devices allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The enable (G\\) input can be used to disable the devices so that the buses are effectively isolated.
The SN54ACT16245 is characterized for operation over the full military temperature range of -55°C to 125°C. The 74ACT16245 is characterized for operation from -40°C to 85°C.
