BU2114F, 8-bit shift register and latch driver

Pin No.

1 2 Symbol SIN CK I/O I I Serial data input pin Shift clock for shift register Setting this pin to "L" holds the latch output.

While it is 3 LATCH I "H", latch output changes simultaneously when the shift register output changes.

4 SOUT O This is the output for the final-stage shift registe

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).
