54ABT16244 16-Bit Buffer/Line Driver with TRI-STATE Outputs July 1998 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 p F and 250 p F 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 m A, source capability of 24 m A Ordering Code: Military 54ABT16244W-QML Package Number WA48A 48-Lead Cerpack Package Description Logic Symbol Connection Diagram Pin Assignment for Cerpack DS100223-1 Pin Description Pin Names OEn I0- I15 O0- O15 Inputs Outputs Description Output Enable Inputs (Active Low) DS100223-2 TRI-STATE ® is a registered trademark of National Semiconductor Corporation. © 1998 National Semiconductor Corporation DS100223 .national. Functional Description The ’ABT16244 contains sixteen non-inverting buffers with TRI-STATE outputs. The device is nibble (4 bits) controlled with each nibble functioning identically, but independent of the other. The control pins can be shorted together to obtain full 16-bit operation.
