Detailed Pin Configuration

The 74ABT16273DGG,512 IC has a total of 48 pins, which are divided into various functional groups: - Data Inputs (A1-A8, B1-B8): These pins receive the input data. - Data Outputs (Q1-Q8, Q9-Q16): These pins provide the output data. - Control Inputs (G, G\~): These pins control the operation of the latch. - Output Enable Inputs (OE, OE\~): These pins enable/disable the outputs. - Latch Enable Inputs (LE, LE\~): These pins control the latching function.

Functional Features

• Transparent Latch: The 74ABT16273DGG,512 acts as a transparent latch, allowing data to pass through when the latch is enabled.
• 3-State Outputs: The IC provides 3-state outputs, allowing multiple devices to share a common bus without interference.
• High-Speed Operation: With a propagation delay of only 4.5 ns, the IC enables fast data transfer.
• Low Power Consumption: The ABT technology used in this IC ensures low power consumption, making it suitable for battery-powered devices.

Advantages and Disadvantages

Advantages: - High-speed operation facilitates quick data transfer. - Low power consumption extends battery life in portable devices. - 3-state outputs enable efficient bus sharing.

Disadvantages: - Limited output drive capability may restrict use in certain applications. - Requires careful handling due to its small size and delicate pins.

Working Principles

The 74ABT16273DGG,512 is a transparent latch that stores and transfers 16 bits of data. When the latch enable (LE) input is high, the input data is passed through to the outputs. When the LE input is low, the outputs retain their previous state. The output enable (OE) input controls whether the outputs are active or in a high-impedance state.
