Edge749 Octal Pin Electronics Driver/Receiver EDGE HIGH-PERFORMANCE PRODUCTS Description The Edge749 is an octal pin electronics driver and receiver combination fabricated in a high-performance CMOS process. It is designed for automatic test equipment and instrumentation where cost, functional density, and power are all at a premium. The Edge749 incorporates eight channels of programmable drivers and receivers into one package. Each channel has per pin driver levels, receiver threshold, and tristate control. The 18V driver output and receiver input range allows the Edge749 to interface directly between TTL, ECL, CMOS (3V, 5V, and 8V), very high voltage, and custom level circuitry. The Edge749 is pin and functionally compatible with the Edge648 and Edge649.
