Driver Specifications for 1 megabyte/second:
•Low State: Output voltage < +0.5V at +48mA sink current
•High State: Output Voltage (3 state) ≥ +2.4V at
The Output Voltage (open collector) is dependent on the composite Device Load Requirements. The Voltage values are measured at the device connector between the signal line and the logic ground.
Mechanical Specifications
Mechanical Specifications comply with IEEE 488.1 standards.
