SN74LVT244BPW

SN74LVT244BPW Description

The SN74LVT244BPW from Texas Instruments is a high-performance non-inverting octal buffer and line driver designed for 3.3V VCC operation. Housed in a 20-pin TSSOP package, it features two 4-bit buffers with separate output-enable (OE) inputs, allowing independent control of each buffer. Operating within a 2.7V to 3.6V supply range, this device is optimized for low-voltage TTL (LVTTL) interfaces, making it ideal for mixed-voltage systems. With 32mA high-level and 64mA low-level output current drive, it ensures robust signal integrity in demanding applications. The device is RoHS3 compliant, REACH unaffected, and has a Moisture Sensitivity Level (MSL) of 1, ensuring reliability in industrial and commercial environments.

SN74LVT244BPW Features

• Dual 4-bit buffers with independent OE controls for flexible signal management.
• Wide operating voltage range (2.7V–3.6V), compatible with 3.3V systems.
• High drive capability: 32mA (high) / 64mA (low), supporting heavy loads.
