FAQs
What is TC74VHCT574AFT?
The TC74VHCT574AFT is an octal D-type flip-flop with 3-state output designed by Toshiba. It is ideal for applications requiring data storage and transfer, such as register banks, address latches, and bus interfacing.
How Does TC74VHCT574AFT Work?
The TC74VHCT574AFT works by storing and transferring digital data using D-type flip-flop elements. Each flip-flop can independently store a binary state, and the 3-state output feature allows the device to effectively isolate itself from the bus lines when it is not actively driving the bus. This is useful for preventing bus contention and reducing power consumption.
How Many Pins does TC74VHCT574AFT have and What are the Functions of the Pinout Configuration?
The TC74VHCT574AFT is housed in a 20-pin TSSOP (Thin Shrink Small Outline Package) package. The pinout configuration includes:
- 1OE: Output enable input pin.
- 1Q to 1Q: Eight outputs for the flip-flop elements.
- 1D to 1D: Eight data input pins for the flip-flop elements.
- GND: Ground pin.
- VCC: Power supply pin.
What are the Pros and Cons of TC74VHCT574AFT?
Pros:
- Data Storage: Provides multiple flip-flop elements for storing digital data.
- 3-State Output: Allows for bus line isolation and reduces power consumption.
- High Density Integration: Packs eight flip-flop elements in a small package, suitable for space-constrained designs.
- Wide Operating Voltage Range: Operates over a wide voltage range for versatile use.
Cons:
- Complexity: Requires careful consideration of timing, bus contention, and bus loading for proper system operation.
- Power Consumption: While the 3-state output reduces power consumption, the overall power draw is still a consideration in some designs.
- Cost: High-density integrated flip-flop devices may have a higher cost compared to simpler alternatives.
Are There Any Equivalents/Alternatives to TC74VHCT574AFT for Recommendation?
- The 74HC574 from NXP Semiconductors is a comparable octal D-type flip-flop with 3-state output.
- Alternatives to the TC74VHCT574AFT include the SN74LVCC3245A from Texas Instruments and the MC74VHC541 from ON Semiconductor.
