Part Number : PA2032A
Function : Pioneer MOSFET
Package : Flexiwatt 27 Pin Type
Description :
Notes about installation and pin number description of Power IC (IC301: PA2032A). The Power IC, PA2032A used on tha Tuner Amp Unit is a 25 pin IC. The same PCB of the Tuner Amp Unit is used for other models that use a 27 pin IC, too. So, the PCB has lands for a 27 pin IC.
When you replace the Power IC, install the Power IC onto 25 pins (2- 26 pin) located in the center of 27 pins for IC301. Therefore, when you check the Power IC on the block diagram, the schematic diagram and the PCB connection diagram, you have to pay attention as follows.

Description :
The PAL007 is a breakthrough BCD (Bipolar / CMOS / DMOS) technology class AB Audio Power Amplifier in Flexiwatt 25 package designed for high power car radio. The fully complementary P-Channel/N-Channel output structure allows a rail to rail output voltage swing which, combined with high output current and minimised saturation losses sets new power references in the car-radio field, with unparalleled distortion performances.

Pericom Semiconductor Corporation
Product Description:
Pioneer Semiconductor’s PI5C series of logic circuits are produced in the Company’s advanced 0.8 micron CMOS technology, achieving industry leading performance.
The PI5C3861 is a 10-bit, 2-port bus switch designed with a low ON resistance (5Ω) allowing inputs to be connected directly to outputs. The bus switch creates no additional propagational delay or additional ground bounce noise. The switches are turned ON by the Bus Enable (BE) input signal.
Product Features:
• Near zero propagation delay
• 5Ω switches connect inputs to outputs
• Direct bus connection when switches are ON
• Ultra Low Quiescent Power (0.2 µA Typical) – Ideally
suited for notebook applications
• Packages available:
– 24-pin 150 mil wide plastic QSOP (Q24)
– 24-pin 300 mil wide plastic SOIC (S24)
