74ABT244
Octal Buffer/Line Driver with 3-STATE Outputs
General Description
The ABT244 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.
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 Disable time less than enable time to avoid bus conten-
tion

Note 9: This specification is guaranteed but not tested. The limits represent propagation delay with 250 pF load capacitors in place of the 50 pF load
capacitors in the standard AC load. This specification pertains to single output switching only.
Note 10: This specification is guaranteed but not tested. The limits represent propagation delays for all paths described switching in phase
(i.e., all LOW-to-HIGH, HIGH-to-LOW, etc.) with 250 pF load capacitors in place of the 50 pF load capacitors in the standard AC load.
Note 11: The 3-STATE delays are dominated by the RC network (500, 250 pF) on the output and have been excluded from the datasheet.
