The NTE75454B is a dual peripheral positive NOR driver in an 8-lead plastic DIP-type package with the output of the logic gates internally connected to the bases of the NPN output transistors designed for use in systems that employ TTL logic. Diode-clamped inputs simplify circuit design. Typical applications include high-speed logic buffers, power drivers, relay drivers, lamp drivers, MOS drivers, line drivers and memory drivers.

Note 1. Voltage values are with respect to network ground terminal unless otherwise specified.
Note 2. This is the voltage between two emitters of a multiple−emitter transistor.
Note 3. Both halves of this dual circuit may conduct rated current simultaneously; however, power dissipation averaged over a short time interval must fall within the continuous dissipation rating.
