description
'ABT543A octal transceivers contain sets D-type latches temporary storage data flowing either direction. Separate latch-enable (LEAB LEBA) output-enable (OEAB OEBA) inputs provided each register permit independent control either direction data flow. A-to-B enable (CEAB) input must enter data from output data from CEAB LEAB low, A-to-B latches transparent; subsequent low-to-high transition LEAB puts latches storage mode. With CEAB OEAB both low, 3-state outputs active reflect data present output latches. Data flow from similar, requires using CEBA, LEBA, OEBA inputs. ensure high-impedance state during power power down, should tied through pullup resistor; minimum value resistor determined current-sinking capability driver. SN54ABT543A characterized operation over full military temperature range -55°C 125°C. SN74ABT543A characterized operation from -40°C 85°C.
