The 74ACT11543DWRG4 is a high-performance, octal bus transceiver and register designed by Texas Instruments that combines D-type latches and D-type flip-flops to allow data flow in transparent, latched, and clocked modes. This integrated circuit (IC) is part of the 74ACT family, which is known for its high-speed CMOS logic operating with an advanced AC series technology.

Key Features

• Logic Type: Octal Bus Transceiver and Register
• Logic Family: 74ACT
• Operating Voltage: 4.5V to 5.5V
• IC Output Type: Tri-State
• Data Flow Control: Transparent, Latched, and Clocked
• Package: SOIC-24 Wide Body (DWRG4)

This device is capable of driving heavily loaded outputs at high speeds, which is perfect for addressing the requirements of high-speed memory receiving and driving. The 74ACT11543DWRG4 is designed to be used in bus-oriented systems where the data flow needs to be controlled effectively, and it operates with a wide range of supply voltages from 4.5V to 5.5V, which is typical for 5V systems.

With its tri-state outputs, the 74ACT11543DWRG4 can be connected directly to a bus-structured system. The tri-state mode also allows for the outputs to be disabled to help prevent bus contention. Moreover, the device features two sets of eight D-type latches with separate latch enable (LE) and output enable (OE) controls for each set. This functionality allows for the flexibility of operation, as the device can be used as two 8-bit transceivers or one 16-bit transceiver.

The IC comes in a 24-pin SOIC package, which is a surface-mount, wide-body package that is suitable for automated assembly processes and space-constrained applications. The 74ACT11543DWRG4 is characterized for operation from -40°C to 85°C, ensuring reliability over a wide range of environmental conditions.

Overall, the 74ACT11543DWRG4 from Texas Instruments is a versatile and reliable component for designers who require high-speed data transfer and storage in their digital systems.
