Description

M34116B1 is the sub package of M34116. The package type is DIP24. The following is the information about M34116.

The M34116 is a kind of PCM conference call and tone generation circuit. M34116B1 is designed for applications in PCM digital exchanges. It can handle up to 64 channels in any conferences
combination from 1 to 29 conferences in parallel and to generate seven different tones and one melody. The M34116 is full pin and function compatible with the M116. Besides, it has the capability to generate tone directly coded in PCM.

What comes next is about the features of M34116B1. First is 1 to 64 serial channels per frame (controlled by SYNC signal period). The second is 29 maximum conferences. Then is 1 to 64 serial channels per conferences. Next is 3 simultaneous operation modes availabe which are conference, transparent and tone generation respectively. The fifth is compatible with all kinds of PCM format. The sixth is equal priority to every channel. The seventh is one frame and one channel delay from sending to receiving. The eighth is total of 7 different tone outputs in parallel programmable via MPU (maximum 4 different frequencies and durations). The last one is TTL compatible input levels and CMOS/TTL compatible output levels.

The following is about the absolute maximum ratings of M34116B1. The VDD (Supply Voltage) is from -0.3 to 7 V. The Vi (Input Voltage) is from -0.3 to VDD V. The VO (off) (Off State Output Voltage) is from -0.3 to 7 V. The Ptot (Total Power Dissipation) is 500 mW. The Tstg (Storage Temperature) is from -65 to 150. The Top (Operating Temperature) 0 to 70.
