SMJ9914A

The SMJ9914A provides an interface between a Microprocessor system and the general purpose interface bus(GPIB) specified in the IEEE-488 1975/78 standards and the IEEE-488A 1980 supplement.The device is controlled and configured through 8-bit memory-mapped registers and enables all aspects of the standards to be implemented,includng talker,listener and controller.

Features of the SMJ9914A are:(1)compatible with IEEE-488A 1980 supplement; (2)talker and listener function(T,TE,L,LE); (3)automatic source and acceptor handshakes(SH,AH); (4)controller with pass control; (5)system controller capabilities; (6)optional automatically cleared 'request service Bk'; (7)single or dual primary addressing; (8)direct-memory-access facilities.

The absolute maximum ratings of the SMJ9914A can be summarized as:(1): supply voltage range(VCC) is -0.3 V to 20 V; (2): all input and output voltage ranges are -0.3 V to 20 V; (3): continuous power dissipation is 1.0W; (4): operating case temperature range is -55 to 110; (5): storage temperature range is -55 to 150.
