SN74LS240 SN74LS244

Octal Buffer/Line Driver

with 3-State Outputs

The SN74LS240 and SN74LS244 are Octal Buffers and Line

Drivers designed to be employed as memory address drivers, clock

drivers and bus-oriented transmitters/receivers which provide

improved PC board density.

• Hysteresis at Inputs to Improve Noise Margins

• 3-State Outputs Drive Bus Lines or Buffer Memory Address

Registers

• Input Clamp Diodes Limit High-Speed Termination Effects
