Serial-Parallel

3-input Driver

BA823F

No.09051EAT01

●Description

BA823F are an 8-bit serial-to-parallel-output driver, applicable for thermal printer heads or LED character display drivers.

●Features

1) Capable of driving a maximum of 200mA.

2) Non-driving current consumption can be reduced by controlling the strobe timing pulse.

3) Output data terminal can be used for a cascade configuration.

4) Digital ground and power ground are separated.

5) TTL and CMOS allow driving.

●Applications

Driver for thermal print head

Driver for LED character display

●Absolute maximum ratings (Ta=25℃)
