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-
sumption.
2) Open drain output.
3) Latch to 8-bit shift register provided, enabling drive
of up to 150mA. (ISINK = 36mA)
4) Cascade connections possible.
•Absolute maximum ratings (unless otherwise noted, Ta = 25°C)
