74ABT543
Octal Registered Transceiver with 3-STATE Outputs
General Description
The ABT543 octal transceiver contains two sets of D-type
latches for temporary storage of data flowing in either
direction. Separate Latch Enable and Output Enable inputs
are provided for each register to permit independent con-
trol of inputting and outputting in either direction of data
flow.
Features
I
Back-to-back registers for storage
I
Bidirectional data path
I
A and B outputs have current sourcing capability of 32
mA and current sinking capability of 64 mA
I
Separate controls for data flow in each direction
I
Guaranteed output skew
I
Guaranteed multiple output switching specifications
I
Output switching specified for both 50 pF and 250 pF
loads
I
Guaranteed simultaneous switching noise level and
dynamic threshold performance
I
Guaranteed latchup protection
I
High impedance glitch free bus loading during entire
power up and power down cycle
I
Nondestructive hot insertion capability
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
