HEF4053B
MSI
The HEF4053B is a triple 2-channel analogue multiplexer/demultiplexer with a common enable input (Ē). Each multiplexer/demultiplexer has two independent inputs/outputs (YO and Y1), a common input/output (Z), and select inputs (SO). Each also contains two-bidirectional analogue switches, each with one side connected to an independent input/output (YO and Y1) and the other side connected to a common input/output (Z).
With E LOW, one of the two switches is selected (low impedance ON-state) by SD. With E HIGH, all switches are in the high impedance OFF-state, independent of SA to SD.
VDD and VSS are the supply voltage connections for the digital control inputs (SA to SC and E). The VDD to VSS range is 3 to 15 V. The analogue inputs/outputs (YO, Y1 and Z) can swing between VDD as a positive limit and VEE as a negative limit. VDD-VEE may not exceed 15 V.
For operation as a digital multiplexer/demultiplexer, VEE is connected to VSS (typically ground).

1. To avoid drawing VDD current out of terminal Z, when switch current flows into terminals Y, the voltage drop across the bidirectional switch must not exceed 0,4 V. If the switch current flows into terminal Z, no VDD current will flow out of terminals Y, in this case there is no limit for the voltage drop across the switch, but the voltages at Y and Z may not exceed VDD or VEE.

M1875 20W Audlo Power Amplifie
The LM 1875 is a monolithic power amplifier offering very low distortion and high quality performance for consumer audio applications.
The LM1875 delivers 20 watts into a 40 or 80 load on ±25V supplies. Using an 80 load and ±20V supplies, over 30 watts of power may be delivered. The amplifier is designed to operate with a minimum of external components. Device overload protection consists of both internal current limit and thermal shutdown.
The LM 1875 design takes advantage of advanced drout techniques and processing to achieve extremely low distortion levels even at high output power levels. Other outstanding features induce high gain, fast slew rate and a wide power bandwidth, large output voltage swing, high current capability, and a very wide supply range. The amplifier is internally compensated and stable for gains of 10 or greater.

bete 1: "Absolute Maximum Ratings" indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits.
βlote 2 . Assumes the use of a heat sink having a thermal resistance of 1°CAV and no insulator with an ambient temperature of 25°C. Because the output limiting directivity has a negative temperature coefficient, the maximum output power delivered to a 4Ω load may be slightly reduced when the tab temperature exceeds 55°C.

The transmission code consists of a leader code, 16-bits custom codes, and 8- bits data codes. The inverse code of the data code is also sent simultaneously. The following diagram shows this one frame construction.
The leader codes consist of a 9 ms carrier waveform followed by a 4.5 ms OFF waveform. It is used as the leader for the following code. Thus, when reception is configured by a microcomputer, the time relationship between the reception detection and other processes can be managed efficiently. The code uses the PPM (Pulse Position Modulation) Method, with "1" and "0" differentiated by the time between pulses. Each code consists of 8 bits, and simultaneous transmission of the inverse code allows configuration of a system with an extremely low error rate.
