SN74ABT646APWR Octal Bus Transceivers and Registers

The SN74ABT646APWR is a high-performance integrated circuit from Texas Instruments designed to provide bidirectional communication and storage functionality in digital systems. It is an essential component for applications requiring efficient data transfer and storage between two buses. This device is part of the ABT family, known for its advanced biCMOS technology, which combines the high speed of bipolar with the low power consumption of CMOS.

The SN74ABT646APWR features eight bidirectional transceivers and D-type flip-flops that can be operated as two separate octal bus transceivers or combined to function as a single 16-bit bus transceiver. Each byte has separate control inputs which can be used to put the output in either a high-impedance state or a low-impedance state, thus enabling the device to interface with different bus configurations.

Key specifications of the SN74ABT646APWR include:

• Logic Type: Octal Bus Transceiver/Register with 3-State Outputs
• Number of Bits per Element: 8
• Number of Elements: 2
• Operating Temperature: -40°C to 85°C
• Mounting Type: Surface Mount
• Package / Case: TSSOP-24
• Supply Voltage: 4.5V to 5.5V
• Logic Level - Low: ≤0.8V
• Logic Level - High: ≥2V

With its dual-functionality, the SN74ABT646APWR can be used in a wide range of applications, including data exchange between different systems, memory buffering, and bus isolation. Its fast data transfer rate and the ability to drive heavily loaded bus lines with up to 64 mA of bus-capable output make it ideal for high-speed data paths in computing and telecommunications systems.

The device is available in a space-saving TSSOP (Thin Shrink Small Outline Package) form factor, making it suitable for compact PCB layouts. Its robust design ensures reliable operation even under challenging conditions, and the extended temperature range makes it suitable for industrial applications.

For designers and engineers looking for a versatile and high-performance solution for bus transceiver and register applications, the SN74ABT646APWR from Texas Instruments stands out as a top choice, delivering both functionality and reliability in a single package.
