8-bit, serial IN, parallel OUT driver
BA829
The BA829 is an 8-bit, serial input, parallel output driver. This is a monolithic IC developed for use in thermal print
heads, LED character displays, and other similar applications.
•Applications
Thermal print head drivers
LED character displays
•Features
1) Can drive up to 300mA.
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 secondary connections.
4) The digital ground and power ground are separated.
5) A latch is included between the shift register and
driver output.
6) A stand-by function is built in.
