These octal buffers and line drivers and designed specifically to
improve both the performance and density of three-state memory address
drivers, clock drivers, and busoriented receivers and transmitters.
This devise features high fan-out, improved fan-in, and 400 mV noise
margin.
It can be used to drive terminated lines down to 133 ohms.
3-State Outputs Drive Bus Lines or Buffer Memory Address Registers
P-N-P Inputs Reduce D-C Loading
Hysteresis at Inputs Improves Noise Margins
