AP471: TTL Level Digital I/O

• TTL-compatible inputs

• 48 bidirectional input/output channels

• 0 to 5V DC

• Wide Temperature Range

• PCIe Bus Interface

AP471 AcroPack I/O (AP) modules provide 48 general-purpose, bidirectional I/O points to economically monitor and control a large quantity of digital devices. Each channel has interrupt capability for detecting low-to-high or high-to-low transitions. Change- of-state interrupts are supported using paired channels. Debounce eliminates interrupts from noise and switching transients for error-free edge detection.
