SN74LVT244BDWR Description

Short technical summary and product information.

The SN74LVT244BDWR is an octal buffer and line driver from Texas Instruments, part of the LVT technology family. It is designed specifically for low-voltage (3.3-V) VCC operation but can provide a TTL interface to a 5-V system environment. The device is organized as two 4-bit line drivers with separate output-enable (OE) inputs. When OE is low, data passes from A inputs to Y outputs; when high, outputs are in high-impedance state.

 

Key electrical specifications include a supply voltage range of 2.7V to 3.6V, maximum output sink current of 64 mA, maximum output source current of -32 mA, and a maximum supply current of 5000 µA. The inputs are TTL-compatible CMOS, and outputs are 3-state. The device supports mixed-mode signal operation (5-V input and output voltages with 3.3-V VCC) and unregulated battery operation down to 2.7V.

 

The SN74LVT244BDWR is offered in a 20-SOIC package (DW code) with dimensions 12.8mm x 10.3mm and surface mount mounting. It operates over an industrial temperature range of -40°C to 85°C. Additional features include over-voltage tolerant inputs, partial power down (Ioff), power-up 3-state support, and hot insertion capability. ESD protection exceeds JESD 22 standards: 2000-V Human-Body Model, 200-V Machine Model, and 1000-V Charged-Device Model. Latch-up performance exceeds 100 mA per JESD 78, Class II.
