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 complete measurement systems.
These transceivers allow the bidirectional flow of digital data and
commands 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 common 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 common Enable input. Again, the terminations are provided.
The MC3443A is identical to the MC3441A except that the ter-
minations have been omitted. As such it is pin compatible, and
functionally equivalent to the SN75138. It does offer the advantage
of receiver input hysteresis.
• Receiver Input Hysteresis Provides Excellent Noise Rejection
• Open-Collector Driver Outputs Permit Wire-OR Connection
• Tailored to Meet the Standards Set by the IEEE and IEC
Committees on Instrument Interface (488-1978)
• Terminations provided (except MC3443A version)
• Provides Electrical Compatibility with General-Purpose
Interface Bus
