Serial-in / Parallel-out Driver Series Serial-Parallel 3-input Driver No.09051EAT01 BA823F 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.
