Product Description

The SN74ALVCH16543DGGR is a versatile integrated circuit that serves as a bidirectional transceiver containing two separate 8-bit units with 3-state outputs. The device can be used in a wide range of applications, including data bus transceivers, signal buffering, and register for temporary storage of data. It is designed to be used with a 3.3 V supply, making it suitable for interfacing with modern low-voltage microprocessors and microcontrollers.

Each 8-bit unit has separate control inputs that can be shorted together for full 16-bit operation. The device features a bus hold on data inputs, which eliminates the need for external pull-up or pull-down resistors and helps in retaining the last active state. The outputs, which are designed to sink significant current, can drive heavily loaded bus lines or buffer memory address registers.

Applications

• Communication systems
• Data bus transceivers
• Memory address drivers
• Buffer registers
• Microprocessor or microcontroller interfacing

The SN74ALVCH16543DGGR is characterized for operation from -40°C to 85°C, ensuring reliability across a wide temperature range, making it an ideal choice for industrial and commercial applications. With its robust design and advanced technology, this Texas Instruments product is engineered to meet the demands of high-speed data communication and processing tasks.
