Detailed Pin Configuration

The SN74LVC16244ADLRG4 has a total of 48 pins, which are divided into four groups of 12 pins each. The pin configuration is as follows:

• Group A (Pins 1-12): Channel 1 Inputs/Outputs
• Group B (Pins 13-24): Channel 2 Inputs/Outputs
• Group C (Pins 25-36): Channel 3 Inputs/Outputs
• Group D (Pins 37-48): Channel 4 Inputs/Outputs

Each group consists of input pins (A1-A12, B1-B12, C1-C12, D1-D12), output pins (Y1-Y12, Y13-Y24, Y25-Y36, Y37-Y48), and control pins (OE1, OE2, OE3, OE4) for enabling/disabling the outputs.

Functional Features

• Non-Inverting Buffer/Driver: The SN74LVC16244ADLRG4 provides non-inverting functionality, meaning that the output signal follows the input signal without any phase inversion.
• 3-State Outputs: The IC has 3-state outputs, allowing the outputs to be disabled or put into a high-impedance state when not in use. This feature enables multiple devices to share a common bus without interfering with each other.
• High-Speed Operation: With a maximum operating frequency of 80MHz and a propagation delay of only 2.5ns, the SN74LVC16244ADLRG4 is suitable for high-speed data transmission applications.
• Wide Voltage Range: The IC operates within a wide voltage range of 1.65V to 3.6V, making it compatible with various low voltage systems.

Advantages and Disadvantages

Advantages: - Non-inverting functionality simplifies circuit design. - 3-state outputs allow for efficient bus sharing. - High-speed operation enables fast data transmission. - Wide voltage range provides compatibility with different systems.

Disadvantages: - Limited number of channels (16) may not be sufficient for certain applications requiring more inputs/outputs. - TSSOP package may require careful handling during assembly due to its small size.

Working Principles

The SN74LVC16244ADLRG4 operates by receiving input signals on its input pins (A1-A12, B1-B12, C1-C12, D1-D12). These input signals are then amplified and non-inverted by internal buffer circuits. The amplified signals are then available at the corresponding output pins (Y1-Y12, Y13-Y24, Y25-Y36, Y37-Y48).

The control pins (OE1, OE2, OE3, OE4) are used to enable or disable the outputs. When the output enable (OE) pin is set to a logic high level, the outputs are enabled and follow the input signals. Conversely, when the OE pin is set to a logic low level, the outputs are disabled and enter a high-impedance state.
