BU4538B

高电压CMOS逻辑IC \u003c功能逻辑\u003e High Voltage CMOS Logic ICs

●Description

BU4015B series ICs are 4-stage static shift registers, each consisting of 2 circuits. The D flip-flops of each stage share a common reset input, enabling asynchronous reset at any time. 

BU4021B series ICs are 8-bit static shift registers configured with 8 register cells, each of which has parallel input.  Control of the parallel/serial input P/S enables serial input/output with clock synchronization and well as parallel input/serial output conversions.

BU4094BC series ICs are shift/store registers, each consisting ofan 8-bit shift register and an 8-bit latch. Output can be held in the data transfer mode because the data read into the shift register can be latched by the asynchronous strobe input, 

The IC is a monostable multivibrator that can be reset and retriggered from either edge of an input pulse.  A wide range of accurate output pulse widths is available because the output pulse width and accuracy are determined by the external timing constants Cx an Rx.

The BU4028B IC is a decoder which converts BCD signals into decimal signals.  

Of the 10 outputs Q0 ~ Q9, those corresponding to the input codes A-D are set to “H”, while the others are set to “L”. 

●Features
