BU2114F

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 equipment, office telephones, audio visual equipment, and expansion input and output boards. Features 1) The CMOS configuration enables low power consumption. 2) Open drain output. 3) Latch to 8-bit shift register provided, enabling drive of up to 150mA. (ISINK = 36mA) 4) Cascade connections possible.
