QUAD GENERAL-PURPOSE INTERFACE BUS (GPIB) TRANSCEIVERS
The MC3440A, MC3441 A, MC3443A are quad bus transceivers intended for usage in instruments and programmable calculators equipped for interconnection into plete measurement systems. These transceivers allow the bidirectional flow of digital data and mands between the various instruments. Each of the transceiver versions provides four open-collector drivers and four receivers featuring input hysteresis.
The MC3440A version consists of three drivers controlled by a mon Enable input and a single driver without an Enable input. Terminations are provided in the device.
The MC3441A differs in that all four drivers are controlled by the mon Enable input. Again, the terminations are provided.
The MC3443A is identical to the MC3441A except that the terminations have been omitted. As such it is pin patible, and functionally equivalent to the SN75138. It does offer the advantage of receiver input...
