4. SpinCore TTL Line Driver Figure 23

A USB-powered device with four input channels and 8 output

lines. Each output line is equipped with current driving capabilities to insure TTL voltage level over 50

Ohm loads. The SpinCore TTL Line Driver is the perfect tool to accompany any TTL device. Additional

specifications, ordering information, and the manual for the TTL Line Driver are available at

http://www.spincore.com/products/SpinCoreTTLLineDriver/SpinCoreTTLLineDriver.shtml

5. If you require a custom design, custom interface cables, or other custom features, please inquire with

SpinCore Technologies through our contact form, which is available at
