Mounting Type: Through Hole
Manufacturer: Rohm Semiconductor
Power (Watts): 600mW
Package / Case: 22-SDIP (0.300", 7.62mm)
Supplier Device Package: 22-SDIP
Function: Pulse, Tone Dialer
Voltage - Supply: 2.5 V ~ 5.5 V
Current - Supply: 660µA
Operating Temperature: -10°C ~ 60°C
Features: ` The chip includes both a pulse and tone dialer, making it possible to dial in either pulse or tone mode.
` A wide operating voltage range enables direct powering by line current. The voltage range guaranteed for both pulse and tone dialing is 2.5V to 5.5V.
` A built-in memory enables redialing of up to 32 digits. Note: In tone mode, the memory itself uses one digit, so please be aware that a maximum of 31 digits can be redialed.
` The chip conforms to the standards of Japan, America, Canada, England, Korea, Taiwan, and Australia.
` The VDD power supply voltage is independent of the DTMF output level.
` There is little deviation in the frequency dividing for the DTMF output frequency. The maximum on the + side is + 0.15%, and on the - side is 0.08%.
