SN74LVT244BDBRE4 - Texas Instruments Octal Buffer/Line Driver

The SN74LVT244BDBRE4 is a high-performance, octal buffer and line driver designed to meet the requirements for improved performance of 3.3-V systems. Manufactured by Texas Instruments, this integrated circuit is part of the SN74LVT family, which is well-known for its low-voltage operation and exceptional speed characteristics. It is specifically designed to be used in applications that require high drive and low output impedance, making it an ideal choice for interfacing with bus lines in a bus-organized system.

With its two separate line driver sections, each with four buffers/line drivers with 3-state outputs, the SN74LVT244BDBRE4 can be employed in a wide range of applications, including memory drivers, clock drivers, and bus-oriented transmitters/receivers. The 3-state outputs, which can be placed in a high impedance state, allow for bus sharing without the risk of bus contention.

The device is characterized for operation from -40°C to 85°C, ensuring reliability and performance across a broad range of operating conditions. The SN74LVT244BDBRE4 comes in a SSOP (Shrink Small-Outline Package) type with a DBR suffix, which is a surface-mount package that is ideal for space-constrained applications.

Key features of the SN74LVT244BDBRE4 include:

• Support for mixed-mode voltage operation on all ports
• 3.3-V VCC operation with 5-V tolerant I/O
• Output drive capability of 64 mA at 3.3 V
• Low power consumption, with 40 µA max ICC
• Input and output edge rate control via ground bounce suppression
• Bus hold on data inputs to eliminate the need for external pull-up/pull-down resistors
• Latch-up performance exceeds 500 mA per JESD 17

Overall, the SN74LVT244BDBRE4 is a versatile and reliable choice for designers who need a high-speed, non-inverting buffer/line driver for their 3.3-V systems. Its robust construction, compatibility with 5-V systems, and power-saving features make it an efficient and durable solution for a variety of digital applications.
