The MC145026 encodes nine lines of information and serially sends this information upon receipt of a transmit enable (TE) signal. The nine lines may be encoded with trinary data (low, high, or open) or binary data (low or high). The words are transmitted twice per encoding sequence to increase security. The MC145027 decoder receives the serial stream and interprets five of the trinary digits as an address code. Thus, 243 addresses are possible. If binary data is used at the encoder, 32 addresses are possible. The remaining serial information is interpreted as four bits of binary data. The valid transmission (VT) output goes high on the MC145027 when two conditions are met. First, two addresses must be consecutively received (in one encoding sequence) which both match the local address. Second, the 4 bits of data must match the last valid data received. The active VT indicates that the information at the Data output pins has been updated. The MC145028 decoder treats all nine trinary digits as an address which allows 19,683 codes. If binary data is encoded, 512 codes are possible. The VT output goes high on the MC145028 when two addresses are consecutively received (in one encoding sequence) which both match the local address. • Operating Temperature Range: – 40 to + 85°C • Very–Low Standby Current for the Encoder: 300 nA Maximum @ 25°C • Interfaces with RF, Ultrasonic, or Infrared Modulators and Demodulators • RC Oscillator, No Crystal Required • High External Component Tolerance; Can Use ± 5% Components • Internal Power–On Reset Forces All Decoder Outputs Low • Operating Voltage Range: MC145026 = 2.5 to 18 V* MC145027, MC145028 = 4.5 to 18 V • Low–Voltage Versions Available: SC41343 = 2.8 to 10 V Version of the MC145027 SC41344 = 2.8 to 10 V Version of the MC145028 • For Infrared Applications, See Application Note AN1016/D PIN ASSIGNMENTS MC145026 ENCODER MC145028/SC41344 DECODERS MC145027/SC41343 DECODERS 13 14 15 16 9 10 11 12 5 4 3 2 1 8 7 6 CTC RTC TE Dout VDD A8/D8 A9/D9 RS A4 A3 A2 A1 VSS A7/D7 A6/D6 A5 13 14 15 16 9 10 11 12 5 4 3 2 1 8 7 6 D9 D8 D7 D6 VDD Din R2/C2 VT A4 A3 A2 A1 VSS C1 R1 A5 13 14 15 16 9 10 11 12 5 4 3 2 1 8 7 6 A9 A8 A7 A6 VDD Din R2/C2 VT A4 A3 A2 A1 VSS C1 R1 A5 * All MC145026 devices manufactured after date code 9314 or 314 are guaranteed over this wider voltage range. All previous designs using the low–voltage SC41342 should convert to the MC145026, which is a drop–in replacement. The SC41342 part number has been discontinued.
