Functional Features

• Octal transparent D-type latch with 3-state outputs
• Provides non-inverting data path for efficient data transfer
• Allows simultaneous updating of all outputs when the latch enable (LE) input is high
• Supports 3-state outputs, allowing multiple devices to share a common bus
• Low-voltage CMOS technology ensures low power consumption and compatibility with various voltage levels

Advantages and Disadvantages

Advantages: - High-speed operation with low propagation delay - Wide operating voltage range - 3-state outputs allow for bus sharing - Compact SOIC package for space-saving designs

Disadvantages: - Limited maximum operating frequency compared to some other ICs - Not suitable for applications requiring very high-speed data transfer

Working Principles

The SN74LVC373AQDWRQ1 operates as an octal transparent latch. When the latch enable (LE) input is high, the data inputs (D0-D7) are transferred to the corresponding outputs (Q0-Q7). The outputs remain in their current state when the LE input is low. The output enable (OE) input controls the 3-state outputs, allowing them to be either active or in a high-impedance state.

Detailed Application Field Plans

The SN74LVC373AQDWRQ1 can be used in various applications, including: - Data storage and transfer in microcontrollers and microprocessors - Address and data bus interfacing in digital systems - Memory address decoding - General-purpose logic level shifting
