Unless otherwise noted, all characteristics are measured with BALANCE and BAL/STRB open and the emitter output grounded.
NOTES:
5. The offset voltages and offset currents given are the maximum values required to drive the collector output up to 14 V or down to
1 V with a pullup resistor of 7.5 k
to VCC+. These parameters actually define an error band and take into account the worst-case
effects of voltage gain and input impedance.
6. The strobe should not be shorted to ground; it should be current driven at –3 mA to –5 mA (see Figures 13 and 27).
