Octal 3-STATE Bus DriverThis octal 3-STATE bus driver DM74ALS244A is designed to provide the designer with flexibility in implementing a bus Interface with memory, Microprocessor or Communication systems. This device offers 64-extended temperature Grade product guaranteeing performance from -40C to +85C. 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 3-STATE circuitry 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.
