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 V^DD, 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

•

3) Latch to 8-bit shift register provided, enabling drive

of up to 150mA. (I^SINK= 36mA)

1) The CMOS configuration enables low power con-

sumption.

4) Cascade connections possible.

2) Open drain output.
