Product Overview: SN74ABT8543DWRE4

The SN74ABT8543DWRE4 is a high-performance integrated circuit designed and manufactured by Texas Instruments. This product is part of the ABT series, which is known for its advanced biCMOS technology. It is specifically crafted to cater to the needs of high-speed digital systems where signal integrity and operational efficiency are of paramount importance.

The SN74ABT8543DWRE4 is a 16-bit transparent D-type latch with 3-state outputs. The device features two sections of eight latches, with each section possessing its own output-enable (OE) input. When OE is low, the device passes the data on the D inputs to the corresponding Q outputs. Conversely, when OE is high, the outputs are in a high-impedance state, which means they neither load the bus nor drive it, allowing multiple devices to be connected to the bus without contention.

This product is designed for 5-V V_CC operation, making it suitable for interfacing with 5V TTL logic levels. Its latch-up performance exceeds 250 mA on the JESD 17 standard, offering robust performance for industrial applications. The SN74ABT8543DWRE4 also boasts a wide operating temperature range, ensuring reliability across diverse environmental conditions.

Key features of the SN74ABT8543DWRE4 include:

• 16-bit transparent D-type latches with 3-state outputs
• Operates from 5V supply
• Output capability: bus driver
• ICC category: MSI
• High-impedance state during power up and power down
• Supports live insertion and withdrawal (partial-power-down mode)

The SN74ABT8543DWRE4 is provided in a wide-body SOIC package, ensuring easy integration into PCB designs and offering excellent thermal performance. It's a perfect choice for applications such as memory address latching, data multiplexing, and as a buffer for bus-oriented systems. Its high-speed and low-power consumption make it an essential component in digital communication, computing, and advanced microprocessor-based systems.

With its combination of speed, power efficiency, and robustness, the SN74ABT8543DWRE4 from Texas Instruments represents a reliable solution for designers looking to optimize their digital systems for performance and reliability.
