Description

The MM54240 is a monolithic MOS integrated circuit utilizing N-channel low-threshold, enhancement mode and ionimplanted depletion mode devices. The circuit MM54240 is designed for processor-type remote control applications. The data transmission consists of a pulse width modulated serial data stream of 18 bits. This stream consists of 7 address bits, 1 command bit, 8 data bits, 1 parity bit and 1 dummy bit in that order.

The MM54240 can be operated in two modes; namely "master'' and "slave''. The master interfaces to a processor bus, and is capable of polling and controlling 128 slave circuits. The slave circuits are interfaced to remote data sources and/or data destinations.
