Product Summary

The DM74ALS244AWMX is an octal 3-STATE bus driver designed to provide the designer with flexibility in implementing a bus interface with memory, microprocessor, or communication systems. The DM74ALS244AWMX offers 64-extended temperature Grade product guaranteeing performance from -40℃ to +85℃. The output 3-STATE gating control is organized into two separate groups of four buffers, and both control inputs enable the respective outputs when set logic LOW. The DM74ALS244AWMX contains a feature that maintains the buffer outputs in 3-STATE (high impedance state) during power supply ramp-up or ramp-down. This eliminates bus glitching problems that arise during power-up and power-down.
