Product Overview: SN74ABT843DBR

The SN74ABT843DBR is a high-performance integrated circuit from Texas Instruments, renowned for its reliability and versatility in various digital applications. This particular IC belongs to the ABT (Advanced BiCMOS Technology) family, which is designed to deliver both the speed of Bipolar with the low power consumption of CMOS technology, making it a perfect fit for interfacing with both bipolar and CMOS circuits.

Key Features

• Technology: Advanced BiCMOS Technology (ABT)
• Logic Type: Synchronous Bidirectional Bus Transceiver
• Package: SSOP (Shrink Small-Outline Package) with 24 pins
• Operating Temperature: -40°C to +85°C, suitable for industrial temperature ranges
• Supply Voltage: 4.5V to 5.5V, ideal for 5V systems
• Speed: Fast propagation delay times
• Drive Capability: Capable of driving ±48-mA IOH and IOL

Functional Description

The SN74ABT843DBR is designed to provide high-speed bidirectional data communication between buses. The control-function implementation minimizes external timing requirements. This device can operate as two 8-bit transceivers or one 16-bit transceiver, with each byte controlled by separate control signals which can be tied together for full 16-bit operation. It features an output-enable (OE) input that can disable the device so that the buses are effectively isolated.

Applications

Thanks to its flexible architecture and high performance, the SN74ABT843DBR is widely used in a variety of applications. These include:

• Telecommunications
• Networking equipment
• High-speed data acquisition systems
• Computers and computer peripherals
