The SN74ABT823DW from Texas Instruments is a high-performance, BiCMOS 9-bit bus interface flip-flop designed with two distinct modes of operation. This integrated circuit is part of the ABT family, which is known for its advanced BiCMOS technology that combines the low power consumption of CMOS with the high speed of bipolar transistors, offering a robust solution for bus interface or buffering applications.

Key Features:

• Logic Type: 9-Bit Bus Interface Flip-Flop
• Package: 24-Pin SOIC (SN74ABT823DW is the wide-body version)
• Operating Temperature: -40°C to +85°C, making it suitable for industrial applications.
• Logic Family: ABT
• Supply Voltage Range: 4.5V to 5.5V, which is typical for 5V logic operations.
• Output Current: Capable of driving ±48 mA at the outputs, providing strong signal driving capability.

Performance:

The device features two modes of operation: transparent mode and clocked (latch) mode. In transparent mode, data on the D-inputs pass through to the outputs when the latch-enable (LE) input is high. In latch mode, the data is latched if LE is low during the low-to-high transition of the clock (CLK). This dual-mode operation provides flexibility in interfacing with bus lines under different control timing scenarios.

Applications:

With its high-speed operation and robust design, the SN74ABT823DW is ideal for use in:

• Data communication systems
• Memory buffering and storage
• Bus interface and drivers
• Microprocessor or microcontroller interface

Quality and Reliability:

Texas Instruments is known for its commitment to quality and reliability, and the SN74ABT823DW is no exception. It is designed to meet or exceed the stringent standards set by the industry, ensuring consistent performance and durability for the end-user. Whether for commercial or industrial applications, this device can be relied upon for its stable operation over a wide range of environmental conditions.
