NOTES
1. The A Grade devices must be used with a heat sink to maintain chip temperature below 1150°C when operating in a TAMB of 1125°C.
2. The temperature coefficients of VOH = 11·2mV/°C, and VOL = 10·24mV/°C but these are not tested.
3. The test configuration for dynamic testing is shown in Fig.5.
4. Tested at 25°C and 1125°C only (170°C for B grade).
5. Tested at 25°C only
6. Tested at 1125°C only (170°C for B grade).

OPERATING NOTES
1. The clock input (pin 4) should be capacitively coupled to the
signal source. The input signal path is completed by connecting
a capacitor from the internal bias decoupling, pin 6, to ground.
2. In the absence of a signal the device will self-oscillate. If this is
undesirable, it may be prevented by connecting a 10kΩ resistor
from the unused input to VEE i.e. from pin 4 to pin 7. This will reduce
the input sensitivity by approximately 100mV.
3. The circuit will operate at very low input frequencies but slew
rate must be better than 200V/µs.

see Fig. 4.
5. The emitter follower outputs require external load resistors.
These should not be less than 330Ω and a value of 430Ω is
recommended. Interfacing to ECLlll/10K is shown in Fig. 7.
6. These devices may be used with split suopply lines and ground
referenced input; a suitable configuration is shown in Fig. 6.
7. All components should be suitable for the frequency in use.
