74ABT373
Octal Transparent Latch with 3-STATE Outputs
General Description
The ABT373 consists of eight latches with 3-STATE out-
puts for bus organized system applications. The flip-flops
appear transparent to the data when Latch Enable (LE) is
HIGH. When LE is LOW, the data that meets the setup
times is latched. Data appears on the bus when the Output
Enable (OE) is LOW. When OE is HIGH the bus output is in
the high impedance state.
Features
s 3-STATE outputs for bus interfacing
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
s Nondestructive hot insertion capability
