General Description
The LVTH543 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 control of inputting and outputting in either direction of data flow.

■ Input and output interface capability to systems at
    5V VCC
■ Bushold data inputs eliminate the need for external
    pull-up resistors to hold unused inputs
■ Live insertion/extraction permitted
■ Power Up/Down high impedance provides glitch-free
    bus loading
■ Outputs source/sink −32 mA/+64 mA
■ Functionally compatible with the 74 series 543
■ Latch-up performance exceeds 500 mA
