SN74LS244NS Description

Short technical summary and product information.

The SN74LS244NS is an octal buffer and line driver designed for use in 5V digital logic systems. It contains two groups of four non-inverting buffers with 3-state outputs, allowing connection to a common bus. The device is part of the 74LS low-power Schottky family, offering a balance of speed and power consumption.

 

Key electrical specifications include a supply voltage range of 4.75V to 5.25V, a maximum propagation delay of 15ns at 5V, and output drive capability of 24mA sink (IOL) and -15mA source (IOH). The inputs are tolerant down to 2V, making them compatible with 3.3V or 2.5V logic inputs. The device draws a maximum supply current of 50mA.

 

The SN74LS244NS is housed in a 20-pin SOIC package (20-SO, 0.209" width, 5.30mm) with surface mount mounting. It is specified for operation over the commercial temperature range of 0°C to 70°C.
