The q denotes specifications which apply over the full operating
temperature range.
Note 1: 3V applied to the Strobe pin will force all outputs low. Strobe pin
input impedance is about 2k to ground. Leave open when not used.
PIN FUNCTIONS
V ^–(Pin 1): Operates – 15V to – 2V.
LOGIC INPUT (Pins 2, 5, 9, 12): Operate properly on TTL
or CMOS levels. Output valid from (V ^– + 2V) ≤ V_IN ≤ 15V.
Connect to 5V when not used.
OUTPUT (Pins 3, 6, 8, 11): Line drive outputs.
ON/OFF (Pin 4): Shuts down entire circuit. Cannot be left
open. For “normally on” operation, connect between 5V to
10V.
GND (Pin 7): Ground must be more positive than V ^–.
STROBE (Pin 13): Forces all outputs low. Drive with 3V.
V ⁺ (Pin 14): Positive supply 5V to 15V.

Note: As with other bipolar ICs, forward biasing the substrate diode can cause
problems. The LT1030 will draw high current from V ⁺ to ground if the V ^– pin is open
circuited or pulled above ground. If this is possible, connecting a diode from V ^– to
ground will prevent the high current state. Any low cost diode can be used.
