• Manufacturer Part Number: BD3401KS2
• Description: Single Power Supply Sound Processor Built-in Pre Amplifier For Tape Recording And Play Back
• Manufacturer: ROHM Co. Ltd.

●Control signal specifications
1.
2.
・Data is read on the rising edge of the clock.
・Latch is read on the falling edge of the clock.
・Latch signal must terminate with the LOW state.
・To avoid malfunctions, clock and data signals must terminate with the LOW state.
・For measurements marked with *, VP-9690A (Average value wave detection, Effective value display) filter by Matsushita
・Phase relation between Input/Output signal terminals is the same (Inputs: pin59-64, pin1-4, Outputs: pin32, 33).
・This IC is not designed to be radiation-resistant.
