The MC74F543 Octal Registered Transceivers contain two sets of data flowing in either direction. Separate Latch Enable (LEAB, LEBA) and Enable (OEAB, OEBA) inputs are provided for each register to permit independent control of inputting and outputting in either direction of data flow. The MC74F543 has a noninverting data path. The A outputs are guaranteed to sink 20 mA while the B outputs are rated for 64 mA.
