Breadboard area for custom circuits
The PCI-1735U digital I/O and counter card is PC-compatible add-on card with 32 digital b channels, 32 digital output channels and three programmable counter/timer channels. The digital I/O channels are TTL-compatible and use 74LS244 driver/buffer circuits to provide high output driving capacity. These buffered circuits also require lower b loading current than regular TTL circuits. The cards’ 8254 programmable counter/timer provides three flexible 16-bit counter/timer channels. You can generate waves and pulses by programming the 8254. Jumper settings determine the clock crystal frequency. The card also includes a breadboard area perfect for customized circuits.
