NOTES: 1. Voltage values are with respect to network GND, unless otherwise specified.
2. This is the voltage between two emitters of a multiple-emitter transistor.
3. This value applies when the base-emitter resistance (R ) is equal to or less than 500 Ω.
BE
4. Both halves of these dual circuits may conduct rated current simultaneously; however, power dissipation averaged over a short time
interval must fall within the continuous dissipation rating.
