SN74BCT244DBRE4 Octal Buffers/Line Drivers with 3-State Outputs

The SN74BCT244DBRE4, manufactured by Texas Instruments, is a high-performance, octal buffer and line driver designed to facilitate bus interface or signal buffering for a wide range of applications. It features eight non-inverting buffers with 3-state outputs, which makes it ideal for driving bus lines or buffering memory address registers.

This integrated circuit (IC) is part of the SN74BCT family, which is known for its improved speed and output drive over equivalent bipolar devices. The SN74BCT244DBRE4 operates from a 4.5V to 5.5V supply, providing a guaranteed output drive while maintaining low power consumption, which is critical for power-sensitive designs.

Key Features:

• Logic Type: Octal Buffer/Line Driver with 3-State Outputs
• Number of Channels: 8
• Supply Voltage Range: 4.5V to 5.5V
• Output Drive: -32mA / 64mA
• Package: SSOP (Shrink Small-Outline Package) with 20 pins
• Operating Temperature Range: -40°C to 85°C
• Logic Level Compatibility: TTL

The SN74BCT244DBRE4 is designed with a high-current output sink capability, which allows for driving heavily loaded outputs with high signal integrity. The 3-state outputs can be put into a high-impedance state, effectively disconnecting the output from the bus or line, which is a necessary feature in shared-bus configurations.

This device comes in a small SSOP package, which is beneficial for space-constrained applications. The pin configuration is optimized to reduce the potential for signal crosstalk, which is essential for maintaining signal fidelity in complex designs.

With its robust design and reliable performance, the SN74BCT244DBRE4 from Texas Instruments is a suitable choice for interfacing with high-speed microprocessors, buffering in bus-oriented systems, and supporting the high-drive requirements of memory and interface applications. Its industry-standard footprint ensures compatibility with many PCB layouts and easy integration into existing designs.

If you require a reliable and efficient octal buffer/line driver for your next project, the SN74BCT244DBRE4 offers the performance and features necessary to meet your design needs.
