FAQs
What is HEF4043BP?
The HEF4043BP is a quad R-S latch with 3-state outputs, designed by NXP Semiconductors. It is ideal for applications requiring multiple latches with 3-state outputs, such as address and data storage, bus interfacing, and general-purpose logic circuits.
How Does HEF4043BP Work?
The HEF4043BP operates as a quad R-S latch, which means it can store four sets of input states and provide 3-state outputs. It can retain its logic state (high or low) even after the inputs are removed, providing memory storage capabilities. The 3-state outputs allow multiple devices to be connected to a common bus without interference.
How Many Pins does HEF4043BP have and What are the Functions of the Pinout Configuration?
The HEF4043BP is housed in a 16-pin DIP (Dual In-line Package) package. The pinout configuration includes:
- 1Q, 2Q, 3Q, 4Q: Individual outputs for the four latches.
- 1Qbar, 2Qbar, 3Qbar, 4Qbar: Complementary outputs for the four latches.
- RS1, SR1, RS2, SR2: Input pins for setting or resetting the latches.
- 1OE, 2OE, 3OE, 4OE: 3-state output enable pins for the four latches.
- GND: Ground pin.
- VDD: Positive power supply pin.
What are the Pros and Cons of HEF4043BP?
Pros:
- Multiple Latches: Contains four R-S latches in a single package, providing space and cost savings in multi-latch applications.
- 3-State Outputs: Enables bus sharing and reduces bus contention in multi-device systems.
- TTL and CMOS Compatible: Can interface with both TTL and CMOS logic families, enhancing compatibility.
- DIP Package: The 16-pin DIP package allows for easy prototyping and soldering onto a circuit board.
Cons:
- Power Consumption: May consume relatively higher power compared to single latches or simple logic gates.
- Propagation Delay: The R-S latch operation may introduce a propagation delay, affecting timing-critical applications.
- Complexity: 3-state outputs and multiple latches may require careful consideration of bus protocols and control logic.
Are There Any Equivalents/Alternatives to HEF4043BP for Recommendation?
- The CD4043 from Texas Instruments is an equivalent quad R-S latch with 3-state outputs.
- Alternatives to the HEF4043BP include the MC14043B from ON Semiconductor and the MM74HC423N from Fairchild Semiconductor.
