1 / 8 page November 1992 Revised January 1999 © 1999 Fairchild Semiconductor Corporation DS011508.prf www.fairchildsemi.com 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 s Back-to-back registers for storage s Bidirectional data path s A and B outputs have current sourcing capability of 32 mA and current sinking capability of 64 mA s Separate controls for data flow in each direction 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 Ordering Code: Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
