54ABT16244 16-Bit Buffer/Line Driver with TRI-STATE ® Outputs
General Description
The ’ABT16244 contains sixteen non-inverting buffers with TRI-STATE outputs designed to be employed as a memory and address driver, clock driver, or bus oriented transmitter/ receiver. The device is nibble controlled. Individual TRI-STATE control inputs can be shorted together for 8-bit or 16-bit operation. n Guaranteed output skew n Guaranteed multiple output switching specifications n Output switching specified for both 50 pF and 250 pF loads n Guaranteed simultaneous switching noise level and dynamic threshold performance n Guaranteed latchup protection n High impedance glitch free bus loading during entire power up and power down cycle n Non-destructive hot insertion capability n Standard Microcircuit Drawing (SMD) 5962-9317402
Features
n Separate control logic for each nibble n 16-bit version of the ’ABT244 n Outputs sink capability of 48 mA, source capability of 24 mA
