The BSPIO-78TTLU is manufactured by GEB Enterprise, and provides a bi-directional parallel-scan access to up to 78 TTL electrical nodes for the driving and sensing of logic values. It features a reliable DIN41612 I/O connector, screw lock brackets, and an operating power of 3.3 V. This 122mmx70mm instrument has 78 LVTTL I/O channels for logic drive and sense and has its I/O organized in 3 segments of 26 pins each. A medium-speed 10MHz TCK is also built in the instrument for high reliability at the best cost/performance ratio.
With a 96 bit boundary-scan register length, each segment of the device can be independently bypassed. Each pin is independently programmable for sense, drive, bi-directional, and tri-state operation.
