... BCD output. They are used with the CA3161E BCD-to-Seven-Segment Decoder/Driver and a minimum of external parts to imple- ment a complete 3-digit display. The CA3162AE is identical to the CA3162E except for an extended operating tempera- ture range. The CA3161E is described in the Display Drivers section of this data book ...

... CA3162E Liquid Crystal Display (LCD) Application Figure 3 shows the CA3162E in a typical LCD application. LCDs may be used in favor of LED displays in applications requiring lower power dissipation, such as battery-operated equipment, or when visibility in high-ambient-light conditions is desired. Multiplexing of LCD digits is not practical, since LCDs must be driven signal and the average voltage across each segment is zero ...

... CA3162E Common-Cathode, LED Display Application Figure 4 shows the CA3162E connected to a CD4511B decode/driver to operate a common-cathode LED display. Unlike the CA3161E, the CD4511B remains blank for all BCD codes greater than nine. After 999mV the display blanks rather than displaying EEE, as with the CA3161E. ...
