BU2114 - 8-bit shift register and latch driver

Description

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.

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.
  • Absolute maximum ratings (unless otherwise noted, Ta = 25°C) Parameter Applied voltage Input voltage Operating temperature Storage temperature Input protection diode current Power dissipation BU2114 BU2114F Symbol VDD VIN Topr Tstg ID Pd Limits.
  • 0.3 ~ + 7.0.

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.
