The SN74HC244DW is an octal buffer and line driver designed by Texas Instruments to enhance the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. This device features two independent 4-bit buffers, each controlled by a separate output-enable (OE) input.
With a wide operating voltage range of 2 V to 6 V, the SN74HC244DW is versatile for various applications. Its high-current outputs can drive up to 15 LSTTL loads, and it provides ±6-mA output drive at 5 V. The typical propagation delay is 11 ns, and it consumes low power with a maximum ICC of 80 µA. The low input current is a maximum of 1 µA.
Designed for surface mounting, the SN74HC244DW comes in a 20-SOIC package with a body size of 12.8mm x 7.5mm. Its 3-state outputs are crucial for driving bus lines or buffer memory address registers. When the OE input is low, data passes noninverted from the A inputs to the Y outputs. When OE is high, the outputs enter a high-impedance state.
Applications for the SN74HC244DW include servers, LED displays, network switches, telecom infrastructure, motor drivers, and I/O expanders. Its robust design and electrical characteristics make it a reliable choice for digital signal buffering and driving tasks.
