• Edge-triggered flip-flops: Captures and stores data on the rising or falling edge of the clock signal.
• Clear input (CLRQ): Resets all flip-flops to a known state.
• Latch enable input (LE): Enables or disables the flip-flop outputs.

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows compatibility with various systems. - Bidirectional translation simplifies interfacing between different logic families. - 3-state outputs facilitate bus sharing and reduce contention issues. - Edge-triggered flip-flops provide reliable data storage.

Disadvantages: - Limited number of flip-flops (8-bit) may not be sufficient for complex applications. - Requires careful consideration of voltage level compatibility to avoid signal degradation or damage.

Working Principles

The 74LVT534D,112 is based on Low Voltage TTL (LVT) technology. It utilizes a combination of voltage level shifting circuits and flip-flops to achieve bidirectional voltage translation. The input signals are latched by the flip-flops on the rising or falling edge of the clock signal. The translated output signals are then driven onto the corresponding I/O pins.
