Description
The GT5910 TTL I/O Module is the typical I/O stage utilized with the GT5150 product. The GT5910 interfaces to the GT5150 and can be configured as Input or Output in groups of 8 I/O pins. Additionally, the GT5910 has on-board terminators that are software controlled (On/Off).
Architecture
The GT5910 employs 2 double-density FCT166245ET transceivers to provide up to 32 channels of bi-directional TTL level I/O. The module supports configurations of 8, 16, and 32 bi-directional channels. On-board register/MUX logic controls the path of data in both input and output modes of operation and determines the output state after a sequencer HALT. SIP sockets provide the optional installation of terminators, 180/390 Ω resistor networks are factory installed.
Programming
The GT5910 Module is controlled by its host, the GT5150, and provides the following programmable functions:
- Global Output Reset
- Tri-state Output on sequencer HALT
- Hold Last Value output on sequencer HALT
- Termination Enable/Disable
- Individual byte enable (4)
Applications
- Default GT5150 I/O module
- TTL applications
- Custom terminations
