HCF4035BEY

Shift Registers Overview

The HCF4035BEY is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology, functioning as a four-stage parallel-in/parallel-out shift register. It features synchronous parallel entry on all stages and serial inputs to the first stage via JK logic. The device includes asynchronous true/complement control on all outputs and an asynchronous common reset. It operates with buffered inputs and outputs, supporting static flip-flop operation in a master-slave configuration. Recommended operating conditions specify a supply voltage range of 3V to 20V and an operating temperature range of -55°C to +125°C.

Shift Registers Feature Summary

• Four-stage clocked signal serial register with provision for synchronous parallel inputs to each stage
• JK input logic provided on the first stage serial input to minimize logic requirements in counting and sequence generation applications
• Asynchronous true/complement control allows availability of true or complement contents at output terminals independent of the clock signal
• Buffered inputs and outputs ensure standardized symmetrical output characteristics

Shift Registers Applications

• Binary to BCD converter circuits
• Bidec logic implementations
• Double sequence generator state sequences
• Shift left/shift right register configurations

Shift Registers Procurement Notes

Verify that the ordering code matches HCF4035BEY for the DIP package variant. Confirm the datasheet version aligns with JEDEC JESD13B standards for B series CMOS devices. Ensure the application environment respects the absolute maximum ratings, particularly regarding power dissipation limits and voltage tolerances relative to VSS pin voltage.

Shift Registers Selection Notes

Select this component when a four-stage shift register with both parallel and serial input capabilities is required. The inclusion of JK logic on the first stage makes it suitable for complex sequence generation without additional external gating. Consider the asynchronous true/complement control feature if simultaneous access to inverted data states is necessary within the system design.

Shift Registers FAQ

How does the JK input logic benefit the first stage?

The JK input logic on the first stage minimizes external logic requirements, particularly in counting and sequence generation applications. When connected together, the first stage functions as a D flip-flop.

What is the function of the True/Complement control?

When high, the true contents of the register are available at the output terminals. When low, the outputs provide the complements of the data in the register. This control functions asynchronously with respect to the clock signal.
