SN74LS244DW Description

Short technical summary and product information.

The SN74LS244DW is an octal buffer and line driver designed for improved performance and density in bus-oriented applications. It features 8 channels with 3-state outputs, making it suitable for driving bus lines or buffering memory address registers.

This device operates within a supply voltage range of 4.75-V to 5.25-V and boasts a high speed with a maximum propagation delay of 15 ns at 5 V. The inputs are tolerant down to 2 V and compatible with 3.3-V or 2.5-V logic levels. The outputs feature 3-state capability, and the device includes PNP inputs to reduce DC loading and hysteresis at inputs for improved noise margins.

The SN74LS244DW is available in various surface mount packages including SOIC (DW), SOP (NS), SSOP (DB), and PDIP (N). It is rated for an operating temperature range of 0°C to 70°C.

This buffer is designed to improve the performance and density of three-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. It offers high fan-out, improved fan-in, and a 400-mV noise margin, and can be used to drive terminated lines down to 133 Ω.
