8-bit, serial IN, parallel OUT driver
BA823 / BA823F
The BA823 and BA823F are 8-bit serial input, parallel output drivers. These monolithic ICs were developed as
drivers for thermal printing heads, LED character displays, and other similar applications.
•
Applications head drivers
Thermal printing
LED character display drivers
•
Features up to 200 mA.
1) Can drive
2) Controlling the strobe terminal with the drive timing
pulse enables current to be reduced when drive is
not being carried out.
3) Using the data output terminal for the next data input
enables cascade connections.
4) The digital ground and power ground are separated.
5) TTL and CMOS drive possible.
