4-BIT BINARY 7-SEGMENT DECODER DRIVER © 4-BIT BINARY CODE INPUT GENERATES 1 TO 16 NUMBERS ON OUTPUT © DIRECT DRIVING OF 1 AND 1/2 DIGIT 7-SEGMENT (COMMON CATHODE) LED DISPLAY © WIDE SUPPLY VOLTAGE RANGE © TTL COMPATIBLE INPUTS © SMALL QUIESCENT SUPPLY CURRENT © SPECIFICALLY DESIGNED FOR TV OR RADIO APPLICATIONS The M 192 is a monolithic integrated circuit which direct drives a 1 and 1/2 digit 7-segment LED (com- mon cathode) display to present the numbers 1 to 16. The inputs accept a 4-bit binary code having TTL levels. This device is especially designed to show the program number in TV or radio sets in conjunction with M 190 keyboard encoder, M 1130 ultrasonic remote control receiver, M 193 electronic program memory or H 770/1/2/3 analog switches. All outputs are designed to supply and sink current, except the additional "r” output (pin 1) which is designed for a brightness control in a current generator con- figurations. The circuit is produced in COS/MOS technology and is supplied in a 16-pin dual in-line plastic package.

J TYPICAL APPLICATIONS (continued) Program display with stand-by indication This application is useful in a remote controlled set. The stand-by condition of the set, i.e. when only the remote control is supplied, is shown by two dots. The program display number is controlled by the same output of the remote control receiver as that which drives the mains relay.
