These buffers/line drivers are designed to improve both the performance and PC board density of TRI-STATE buffers/drivers employed as memory-address drivers, clock drivers, and bus-oriented transmitters/receivers. Featuring 400 mV of hysteresis at each low current PNP data line input, they provide improved noise rejection and high fanout outputs and can be used to drive terminated lines down to 133 ohms.
TRI-STATE outputs drive bus lines directly
PNP inputs reduce DC loading on bus lines
Hysteresis at data inputs improves noise margins
Typical enable/disable time 18 ns
20 pin DIP. Manufactured by National.
