remote transmitter applications
PCA84C922; PCA84C923
10 PORT OPTIONS
Ports can be configured using one of three mask options.
The three I/O mask options are specified below.
Option 1 Standard I/O with switched pull-up current
source; this is shown in Fig.16.
Option 2 I/O with open-drain output; this is shown in
Fig.17.
Option 3 Push-pull output; this is shown in Fig.18.
The state of the ports and the LOUT pin after a
Power-on-reset can also be selected using mask options.
All mask options are given in Table 8.

Notes to Table 8
1.
If diodes are used for system selection the scan lines
(Port 0 and Derivative Port 6) cannot take Option 3.
2.
Scan lines should have the option ‘1R’.
3.
Sense lines should have the option ‘1S’.
4.
Only the PCA84C923D has external Derivative Port 6
terminals and therefore this option is only valid for this
device. The other members of the range have the state
of their internal Derivative Port 6 latch fixed at ‘1S’.
