(1) Unless otherwise noted, all characteristics are measured with BALANCE and BAL/STRB open and EMIT OUT grounded.
Full range is –40 ° C to 125 ° C for Q temp and -55 ° C to 125 ° C for M temp.
(2) All typical values are at T
A
= 25 ° C.
(3) 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 Ω to V
CC+
. These parameters actually define an error band and take into account the worst-case effects of
voltage gain and input impedance.
(4) The strobe should not be shorted to ground; it should be current driven at –3 mA to –5 mA (see Figure 13 and Figure 27 ).

(1) The response time specified is for a 100-mV input step with 5-mV overdrive and is the interval between the input step function and the
instant when the output crosses 1.4 V.
