PCI-1735U 64-ch Digital I/O and Counter Universal PCI Card Features ISA-Compatible with PCL-720+ 32 TTL-level digital input channels 32 TTL-level digital output channels High-output driving capacity Low-input loading 3 programmable counter/timer channels User configurable clock source Breadboard area for custom circuits Introduction The PCI-1735U digital I/O and counter card is PC-compatible add-on card with 32 digital input channels, 32 digital output channels and three programmable counter/timer channels. Their 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 input 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.
