MC74F544

MC74F544 OCTAL REGISTERED TRANSCEIVER, INVERTING, 3-STATE The MC74F544 Octal Registered Transceivers contain two sets of D-Type latches for temporary storage 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 MC74F544 has an inverting data path. The A outputs are guaranteed to sink 24 mA while the B outputs are rated for 64 mA.
