Encoder and Decoder Pairs

CMOS

Legacy Device: Motorola/Freescale MC145026, MC145027, MC145028

These devices are designed to be used as encoder/decoder pairs in remote

control applications.

The ML145026 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.

CASE 648

The ML145027 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 trans-

mission (VT) output goes high on the ML145027 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.

CASE 751G

The ML145028 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 ML145028 when two addresses are consecu-

tively received (in one encoding sequence) which both match the local

address.

• Operating Temperature Range: T = – 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

Note: Lansdale lead free (Pb) product, as it

becomes available, will be identified by a part

number prefix change from ML to MLE.

• High External Component Tolerance; Can Use 5% Components

• Internal Power–On Reset Forces All Decoder Outputs Low

• Operating Voltage Range: ML145026 = 2.5 to 18 V*

ML145027, ML145028 = 4.5 to 18 V

• For Infrared Applications, See Application Note AN1016/D
