NTE742 Integrated Circuit TV Sound Channel, 2W Description: The NTE742 is designed for use as the entire sound function in television receivers or FM table radios. The NTE742 sound channel will directly drive a 16 ohm speaker with more than 2 watts output. This monolithic integrated circuit will operate from a single 18V to 28V power supply and can also function (with reduced power output) with supplies as low as 12V if additional decoupling is provided. The NTE742 is supplied in an improved 16–lead plastic dual in–line package with heat–sink contact tabs. A copper alloy lead frame allows maximum power dissipation with standard cooling methods. The unique lead configuration allows easy attachment of a heat sink and yet permits the use of a standard IC socket or printed wiring board layout.
