Datasheet SN74LS47 Equivalent ( PDF ) - Driver

SN74LS47 BCD to 7-Segment Decoder, Driver The SN74LS47 are Low Power Schottky BCD to 7-Segment Decoder, Drivers consisting of NAND gates, input buffers and seven AND-OR-INVERT gates. They offer active LOW, high sink current outputs for driving indicators directly. Seven NAND gates and one driver are connected in pairs to make BCD data and its complement available to the seven decoding AND-OR-INVE

The SN7101 is integrated a high stability band gap voltage reference, two ORed operational amplifiers and a current source. This IC compares the DC voltage and the current level at the output of a switching power supply to an internal reference.

It provides a feedback through an Opto-coupler to the PWM controller IC in the primary side. The controlled current generator can be used to modify the level of current limitation by offsetting the information coming from the current sensing resistor.

The SN7103 is a monolithic IC that includes one independent op-amp and another op-amp for which the non inverting input is wired to a 2.5V fixed Voltage Reference.
