Disadvantages: - Limited output current capability compared to some other ICs - Requires external clock signal for proper operation - Not suitable for applications requiring high output capacitance

Working Principles

The SN74ABT373N operates as an octal transparent latch with 3-state outputs. When the latch enable (LE) input is high, the data inputs (D0-D7) are transferred to the corresponding outputs (Q0-Q7). The latch holds the data until a new set of inputs is provided.

The output enable (OE) input controls the output state. When OE is low, the outputs are in the high-impedance state, allowing multiple devices to share a common bus. When OE is high, the outputs reflect the stored data.

Detailed Application Field Plans

The SN74ABT373N is widely used in various digital systems, including but not limited to: - Microprocessors and microcontrollers - Data storage systems - Communication devices - Industrial control systems - Automotive electronics
