SN74LS244DBR Description

Short technical summary and product information.

The Texas Instruments SN74LS244DBR is an 8-channel bus buffer and line driver designed for digital logic systems. It features non-inverting buffers with 3-state outputs, enabling bus-oriented applications. The device operates from a 4.75V to 5.25V supply voltage and provides output current drive capability of 15 mA (minimum) to 24 mA (maximum). Maximum propagation delay is 15 ns at 5V, making it suitable for high-speed data transmission. PNP inputs allow input thresholds down to 2V, and the device is compatible with 3.3V or 2.5V logic levels. Input hysteresis improves noise immunity. The SN74LS244DBR is housed in a 20-pin SSOP (0.209", 5.30mm Width) surface-mount package with an operating temperature range of 0°C to 70°C. Typical applications include memory address driving, bus transceiver interfaces, and signal buffering in microcontroller-based systems.
