The BU2114 and BU2114F are CMOS ICs with low power consumption, and are equipped with an 8-bit shift register latch. Data in the shift register can be latched asynchronously. The outputs (O1 to O8) are open drain outputs (because there is no protection diode, a maximum voltage above VDD, of up to 7V, can be applied), and one output can drive 36 mA. A total output of up to 150 mA can be driven (when using static operation).
