SN74ABT16543DLG4: 16-Bit Bus Transceivers and Registers

The SN74ABT16543DLG4 is a high-performance, integrated circuit designed and manufactured by Texas Instruments. This device is a member of the ABT family, which is known for its advanced biCMOS technology. It serves as a versatile 16-bit bus transceiver with 3-state outputs, featuring two separate 8-bit bus transceivers with 3-state outputs in each byte. The product is aimed at applications that require high-speed bidirectional communication between data buses.

The SN74ABT16543DLG4 provides two sets of eight D-type flip-flops that can act as either transceivers or registers, allowing for flexible data handling in a variety of system configurations. Each set operates independently, with separate control, direction, and output-enable signals, making it suitable for interfacing with different logic levels or providing isolation between two buses.

Key features of the SN74ABT16543DLG4 include:

• Support for mixed-mode signal operation, with the ability to shift between 5-V TTL and 3.3-V CMOS logic levels.
• High drive capability, with -32 mA IOH and 64 mA IOL, which is essential for driving capacitive loads or multiple receivers.
• Low power consumption, a characteristic of the ABT series, which minimizes power draw in sensitive applications.
• Robust design with latch-up performance that exceeds 250 mA per JESD 17, ensuring stability and reliability.
• ESD protection exceeding JESD 22, safeguarding the device during handling and operation.

The SN74ABT16543DLG4 is packaged in a 48-pin DLG type surface-mount package, which helps to conserve space on printed circuit boards. It is designed for use in a wide range of applications, including memory buffering, data transmission, and digital signal processing. With its high-speed data transfer capabilities and robust design, the SN74ABT16543DLG4 is an ideal choice for designers who require a reliable and efficient interface for their digital systems.

Overall, the SN74ABT16543DLG4 from Texas Instruments stands out as a high-quality, versatile component suitable for sophisticated digital applications where performance and reliability are paramount.
