74LS244 Octal Driver Tri-State [Original]

74LS244 Octal Tri-State Buffer & Line Driver IC (Original)

The 74LS244 Octal Tri-State Buffer & Line Driver IC is a high-performance integrated circuit designed for robust digital data transmission. It significantly enhances both system performance and PC board density in your designs. Featuring tri-state outputs, this IC allows direct connection to bus lines without requiring external components. Its PNP inputs effectively minimize DC loading on bus lines, preserving signal integrity. Each data line input incorporates 400 mV of hysteresis, ensuring excellent noise rejection in challenging environments. This makes the 74LS244 ideal for critical applications like memory-address and high-speed clock drivers. Designed as a bus-oriented transmitter/receiver, it guarantees reliable communication across diverse systems. This original 74LS244 offers standard TTL switching voltages, ensuring broad compatibility with existing logic circuits.
