Standard ICs 8-bit shift register and latch driver BU2114 / BU2114F 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). Applications • These are designed for a wide range of applications in microcomputer peripheral circuits, such as in industrial equip- ment, office telephones, audio visual equipment, and expansion input and output boards. Features • 1) The CMOS configuration enables low power con- 3) Latch t
