Overview

~National D Semiconductor JULY 1978 INS8254 N-Channel Bit Programmable Per~pherallnterface.

Key Features

  • The INSS254 is an LSI device which provides two S-bit ports of peripheral interfacing capability for microcomputer systems. The I/O chip contains two peripheral ports of eight bits each. Each of the I/O pins in the two ports may be defined as an input or an output to provide maximum flexibility. Each port may be read from or written to in a parallel (S-bit byte) mode. To improve efficiency and simplify programming in control-based.
