74ABT541
Octal Buffer/Line Driver with 3-STATE Outputs
General Description
The ABT541 is an octal buffer and line driver with 3-STATE
outputs designed to be employed as a memory and
address driver, clock driver, or bus-oriented transmitter/
receiver. The ABT541 is similar to the ABT244 with broad-
side pinout.
Features
s Non-inverting buffers
s Output sink capability of 64 mA, source capability of
32 mA
s Guaranteed output skew
s Guaranteed multiple output switching specifications
s Output switching specified for both 50 pF and 250 pF
loads
s Guaranteed simultaneous switching, noise level and
dynamic threshold performance
s Guaranteed latchup protection
s High impedance, glitch free bus loading during entire
power up and power down cycle
s Nondestructive hot insertion capability
s Flow-through pinout for ease of PC board layout
s Disable time less than enable time to avoid bus
contention
