54ABT541 Octal Buffer/Line Driver with TRI-STATE Outputs
General Description
The ’ABT541 is an octal buffer and line driver with TRI-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 broadside pinout. n Guaranteed latchup protection n High impedance glitch free bus loading during entire power up and power down cycle n Nondestructive hot insertion capability n Flow-through pinout for ease of PC board layout n Disable time less than enable time to avoid bus contention n Standard Microcircuit Drawing (SMD) 5962-9471801
Features
n Non-inverting buffers n Output sink capability of 48 mA, source capability of 24 mA
