Functional Features

• Octal transparent latch with 3-state outputs
• Data inputs (D0-D7) are latched to the outputs (Q0-Q7) when the latch enable (LE) signal is high
• The output enable (OE) signal controls the 3-state outputs, allowing them to be in a high-impedance state when disabled
• TTL-compatible inputs ensure compatibility with various logic families
• High-speed operation enables efficient data transfer

Advantages and Disadvantages

Advantages

• Provides efficient storage and control of data in bus-oriented applications
• Wide operating voltage range allows for compatibility with different power supply levels
• High-speed operation ensures fast data transfer
• 3-state outputs facilitate bus sharing and reduce contention issues

Disadvantages

• Limited number of bits (8) may not be sufficient for certain applications requiring larger data storage capacity
• Requires external control signals (LE and OE) for proper operation, which adds complexity to the system design

Working Principles

SN74BCT373N operates based on the principles of latch-based storage and control. When the latch enable (LE) signal is high, the data inputs (D0-D7) are latched to the outputs (Q0-Q7). The output enable (OE) signal controls the 3-state outputs, allowing them to be in a high-impedance state when disabled.
