NTE1691 & NTE1692
Integrated Circuit
Telephone Pulse Dialer w/Redial
Description:
The NTE1691 and NTE1692 are monolithic CMOS integrated circuits in an 18–Lead DIP type package
that provide all the features required for implementing a pulse dialer with redial.
Functions:
D Mute Output Logic “0”
D Pulse Output Logic “0”
D RC Oscillation for Reference Frequency
D Designed to Operate Directly from the Telephone Line
D Used CMOS Technology for Low Voltage, Low Power Operation
D Power Up Clear Circuitry
D NTE1691 Pin2: VREF
D NTE1692 Pin2: Tone Out
Features:
D Uses Either a Standard 2 of 7 Matrix Keyboard with Negative True Common or the Inexpensive
Form A–Type Keyboard
D Make/Break Ratio Can Be Selected
D Redial with * or #
D Tone Signal Output or On–Chip Reference Voltage by Bonding Option on Chip
D 10pps/20pps Can be Selected
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
