| TECHNICAL DATA IL91260C 10 Memory Tone/Pulse Dialer High-Performance Silicon-Gate CMOS The IL91260C is tone/pulse switchable dialer with ten 16-digit number memories and 32-digit redial memory. Pulse to tone mode switching is performed via a slide switch. * 32-digit redial memory (31 digits in tone mode) * Ten indirect memories, 16 digits in pulse mode, 15 digits in tone mode * Tone/Pulse mode switching via slide switch (4.1 second pause inserted automatically) * Wide operating voltage: 1.8 V 5.5 V * Uses 480 KHz ceramic resonator * Low memory retention current * Selectable Make/Break ratio * Dial Pulse Rate: 10 pps ORDERING INFORMATION IL91260CN TA = -20 to 70 C PIN ASSIGNMENT LOGIC DIAGRAM PIN 11 = GND PIN 10 = VCC Keyboard Assignments* 1 4 7 * C1 2 5 8 0 C2 3 6 9 # C3 S A/L P R C4 R1 R2 R3 R4 S A/L P R : Store : Auto/Location : Pause : Redial IL91260C Pin Description Pin No. 1 2 3 4 5 Designation R1 R2 R3 R4 HK Hook switch input. When HK = VCC, an ON-Hook state exists. When HK = GND, an Off-Hook state exists. Dial pulse Make/Break ratio select input. If M/B = VCC , the Make/Break ratio is 1/2. If M/B = GND, the Make/Break ratio is 2/3. Pulse/DTMF mode select input. If MODE SELECT = VCC , Pulse mode is in effect. If MODE SELECT = GND, DTMF mode is in effect. Oscillator I/O. A 480 KHz ceramic resonator and two 100 pF serial loading capacitors form a complete oscillator circuit. The circuit is activated when HK is low. Oscillator start-up time is typically 10 ms. Description Keyinputs. When a row and a column are connected, a key operation is activated. Scanning signals are present on both the row and column pins during a valid key-in condition. 6 M/B 7 MODE SELECT 8 9 OSCI OSC0 10 11 12 VCC GND TONE Positive power supply. Negative power supply. DTMF signal output. Pull-down load resistance is 10,000 . The minimum tone and IDP durations are built-in for both normal dialing and redialing. Transmit mute output. This is an N-channel open drain output. The output transistor is switched on while a sequence of digits is being dialed (for both Pulse and Tone modes). Otherwise, it is switched off. Dial pulse output. This pin is an N-channel open drain output. When DP output is low (switched on), it serves as a break signal in Pulse dialing. For other operations, DP output is normally high impedance (switched off). Keyinputs. When a row and a column are connected, a key operation is activated. Scanning signals are present on both the row and column pins during a valid key-in condition. 13 XMUTE 14 DP 15 16 17 18 C1 C2 C3 C4 TECHNICAL DATA Operation Procedures Symbol Definitions: a.

DTMF Generator The digitally synthesized sinewave of the IN91260 series is well designed, with a 6 level, 12 segment, 1/2 VCC reference voltage. The THD (Total Harmonic Distortion) of the DTMF output is typically 1%, when VCC = 2.5 V to 5.5 V and frequency is in the 500 HZ to 3400 HZ band.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND(VIN or VOUT)VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open.
