UM91611 General Description
The UM91611 pulse dialer is monolithic CMOS integrated circuit which convbrt pushbutton inputs to a series of pulses suitable for telephone dialing.The UM91611 is pin compatible with T25610 and quite similar to UM91610.The UM91611, is upgrated version of the popular UM9151.In addition to;dialer functions performed by the UM9151,UM91611 has ten 18-digit number memories plus last number redial memory with 22-digit capacity.
Features of the UM91611 are:(1)ten 18-digit number memories plus last number radial memory (22 digit) memory on chip;(2)low voltage CMOS process for direct operation from telephone lines;(3)inexpensive= RC oscillator design with accurary better than f5% over temperature and unit-unit variations;(4)uses either inexpensive single contact XY matrix key-board or standard 2 of 7 keyboard with positive common;(5)mute and pulse drivers on chip.CMOS technology is used to produce this device, resulting in very low power requirements, high noise immunity,and easy interface to a variety of telephones requiring few external components.
The absolute maximum ratings of the UM91611 can be summarized as:(1)operating temperature:-20 to +60°C;(2)storage temperature: -55 to 125°C;(3)DC supply voltage(Vdd-Vss):-0.3 to +5.0V;(4)applied voltage on any pin:Vss-0.3VinVdd+0.3V.Stresses above those listed under "absolute maximum ratings" may cause permanent damage to the device.This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.The UM91611 is Make first and Break next structure.When the first digit in RAM is dialed, a logic circuit check immediately if a next digit should dial out. And an interdigit pause will be wait if a next digit is waiting to send out or the oscillator will he disable immediately.Essentially the UM91611 uses a post-digit pause to meet the EIA RS-470 inter-digit pause requirement.
At present there is not too much information about this model.If you are willing to find more about UM91611, please pay attention to our web! We will promptly update the relevant information.
