• Pins 33 to 36: Voltage supply (VCC) pins
• Pins 37 to 44: Data output (DO) pins for the 16-bit data bus
• Pins 45 to 48: 3-state output control (OCT) pins for each of the four output ports

Functional Features

• High-speed operation: The SN74ALVCH162373KR can operate at high frequencies, making it suitable for applications requiring fast data transfer.
• Low-voltage operation: With a supply voltage range of 1.65V to 3.6V, this IC is designed to work with low-power systems.
• 3-state outputs: The 3-state output control allows the outputs to be disabled, enabling multiple devices to share a common bus without interference.
• Transparent latch function: The latch enable (LE) pins allow the data inputs to be transparently transferred to the outputs when enabled.

Advantages and Disadvantages

Advantages: - High-speed data transfer capability - Low-voltage operation for power-efficient designs - 3-state outputs for bus sharing applications - Transparent latch function for easy data transfer

Disadvantages: - Limited to 16-bit data bus applications - Requires external components for proper operation - Sensitive to electrostatic discharge (ESD)

Working Principles

The SN74ALVCH162373KR operates by latching the input data onto its internal registers when the latch enable (LE) pins are activated. The latched data is then transferred to the output pins when the output enable (OE) pins are enabled. The 3-state output control (OCT) pins allow the outputs to be disabled, effectively disconnecting them from the bus.

Detailed Application Field Plans

The SN74ALVCH162373KR can be used in various applications, including:

1. Data storage systems: It can be used to store and transfer data between different components of a system, such as microcontrollers, memory modules, and peripherals.
2. Communication systems: It can facilitate data transfer between different communication modules, such as UARTs, Ethernet controllers, and wireless transceivers.
3. Industrial automation: It can be employed in control systems to handle data exchange between sensors, actuators, and programmable logic controllers (PLCs).
4. Automotive electronics: It can be utilized in automotive applications, such as in-vehicle networks, infotainment systems, and engine control units (ECUs).
