Overview and Applications  
Pattern I/O and Handshaking I/O  
With pattern I/O, you can input or output  
patterns under timing control of a clock  
BUY ONLINE!  
The NI 653x devices are high-speed, 32-bit, parallel, digital I/O  
interfaces for PCI, PXI, PCMCIA, and ISA. They incorporate the  
National Instruments DAQ-DIO ASIC, specifically designed to deliver  
high performance on plug-in DIO devices. The NI 653x devices perform  
unstrobed I/O, pattern I/O, and handshaking at speeds up to  
20 MHz, or 80 Mbytes/s for 32-bit transfers (NI 6534). The NI 6534  
family delivers digital I/O coupled with large onboard memory for high-  
speed pattern I/O at deterministic rates.  
signal. When using handshaking I/O to interface your NI 653x to a  
peripheral device, data is transferred when both the NI 653x and the  
peripheral are ready. See page 376 in the Digital I/O overview and  
page 787 in the Digital I/O tutorial for more information.  
Change Detection  
You can program the 653x devices to acquire data when one or  
more user-specied digital input lines changes state. See page  
377 in the Digital I/O overview and page 787 in the Digital I/O  
tutorial for more information.  
Features  
Data Latches and Drivers  
The 32 digital I/O lines are divided into four 8-bit ports. For pattern  
I/O or handshaking, the ports can be grouped into two 8-bit or  
16-bit groups, or a single 32-bit group. When configured for output,  
each data line can sink or source up to 24 mA when set logic low or  
high, respectively. When configured as inputs, the 653x data lines  
are diode-terminated to dampen the input signals at TTL levels.  
When performing static or unstrobed I/O, you can individually  
configure each of the 32 I/O lines as input or output.
