SN74LVT244BDB Description

Short technical summary and product information.

The SN74LVT244BDB from Texas Instruments is an octal buffer and line driver designed for 3.3V VCC operation, offering a TTL interface to a 5V system environment. This device features two 4-bit line drivers, each with a separate output-enable (OE) input. When OE is low, data passes from the A inputs to the Y outputs; when OE is high, the outputs enter a high-impedance state.

 

Key electrical specifications include a supply voltage range of 2.7V to 3.6V, with a nominal operating voltage of 3.3V. It supports output drive currents of -32mA and 64mA, and operates at a maximum clock frequency of 160MHz with a propagation delay of 3.5ns at 3.3V. The quiescent current is a low 0.005mA at 3.3V.

 

This buffer/driver is suitable for mixed-mode signal operation, supporting both 5V input and output voltages with a 3.3V VCC. It also supports unregulated battery operation down to 2.7V. The device is organized into 2 elements, each with 4 bits per element.

 

The SN74LVT244BDB is available in a 20-SSOP surface mount package with dimensions of 5.30mm width. It operates within an ambient temperature range of -40°C to 85°C. The component is RoHS3 compliant and has a Moisture Sensitivity Level (MSL) of 1.
