Single-chip-pulse-tone-dialer
The XR-T5990 single-chip pulse/tone dialer is a silicon gate CMOS circuit that performs both pulse and tone dialing functions. It is designed to operate directly from the telephone line or from a separate small power supply. Additionally, a 17-digit buffer is included for a redial feature.
The XR-T5990 is a versatile integrated circuit that facilitates the dialing of telephone numbers using both pulse and tone signaling methods. The capability to operate directly from the telephone line enhances its utility in various applications, eliminating the need for an external power source in certain scenarios. This feature is particularly beneficial in designs where simplicity and space efficiency are paramount.
In terms of functionality, the XR-T5990 supports a 17-digit buffer, which is critical for enabling the redial feature. This buffer allows users to store the last dialed number, making it convenient to reconnect to frequently called contacts without re-entering the number manually. The CMOS technology employed in the design ensures low power consumption, making it suitable for battery-operated devices as well.
The circuit can be integrated into various telecommunications equipment, such as landline telephones, intercom systems, and other communication devices requiring dialing capabilities. The flexibility of operating from either the telephone line or a dedicated power supply allows for a wider range of applications, accommodating different design requirements and constraints.
Overall, the XR-T5990's combination of pulse/tone dialing functionality, redial capability, and efficient power operation makes it a valuable component in modern electronic communication systems.The XR-T5990 single-chip pulse/tone Dialer is a silicon gate CMOS circuit which performs both pulse and tone functions.
