CH421DS1.PDF
|
CH421 datasheet. Bidirectional buffer interface chip. The CH421 supports parallel port communication, asynchronous data exchange, no need to synchronization or waiting during read/write operations. The maximum transfer speed is not less than 7Mbytes per second. It can be used for 8-bit parallel port exchange data between two MCUs. |
