TECHNICAL DATA IL6965 Telephone Speech Network with Dialer Interface The IL6965 is a bipolar integrated circuit for use in electronic telephones. The IL6965 has low operating voltage, it provides an excellent branch performance. It has line voltage increasing circuit by the external terminal. Transmitting and receiving gains automatically vary according to the line current. ORDERING INFORMATION IL6965N Plastic DIP IL6965D Plastic SOIC TA = -30° to 70° C FEATURES PIN ASSIGNMENT • Externally adjustable transmitting, receiving and sidetone gains. • Switching between transmitting output and DTMF output is possible. • Direct interface with light and compact ceramic transmitter-receiver is possible. • Receiver follow impedance type can also be used. • Gain is automatically controlled according to the line current. (Auto-PAD function) • The line voltage can be increased by the external terminal (Up function). • PKG is 20pin DIP & SOP 1 IL6965 BLOCK DIAGRAM 2 IL6965 3 IL6965 4 IL6965 5 IL6965 6 IL6965 7 IL6965 8 IL6965 9 IL6965 10 IL6965 11 IL6965 12 IL6965 13 IL6965 14 IL6965 15 IL6965 IL6965 16 IL6965 17 IL6965 18 IL6965 19 IL6965 20 IL6965 21 IL6965 22 IL6965 23 IL6965 N SUFFIX PLASTIC DIP (MS - 001AD) A Dimension, mm 11 20 B 1 10 Symbol MIN MAX A 24.89 26.92 B 6.10 7.11 5.33 C F L C -T- SEATING PLANE D 0.36 0.56 F 1.14 1.78 G 2.54 H 7.62 N G K M J H D 0.25 (0.010) M T NOTES: 1.
