Infrared Remote Control Receiver PT2249A / PT2250A Series
PT2249A/50A v 2.3
Page 4 Revised Dec. 1999
Application Note:
1. Combination of PT2248/PT2249A Series Code Bits
a) PT2249A Series Code Bit C1 is internally pulled high and thereby set
at a default value of “1”. Thus, PT2248 Code Bit C1 must be set at “1”.
b) PT2249A Series Code Bits C2 and C3 may be programmed as follows:
1) “0”, “0” (This combination is not available with TC9149.)
2) “0”, “1”
3) “1”, “0”
4) “1”, “1”
c) To set Code Bit to “1” on PT2248, diodes must be connected to Code
Terminal from the T1 ~ T3 terminals.
d) To set Code Bit to “0” on PT2248, the terminals must be kept floating,
except C1 - add one diode.
e) The Code Bits Combinations of PT2248 and PT2249A Series are shown
below:

f) Example : (Refer to Example 1 diagram)
The following example shows the case when PT2248 Code Bits C1 = 1,
C2 = 1, and C3 = 0. The CODE2 Pin of the PT2249A Series is
programmed in floating state and CODE3 pin is connected to Vss (C2 = 1,
