74LVC543A Octal D-type Registered Transceiver; 3-state

The 74LVC543A is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families. The 74LVC543A is an octal registered transceiver containing two sets of D-type Latches for temporary storage of the data flow in either direction. Separate latch enable inputs (pins LEAB and LEBA ) and output enable inputs (pins OEAB and OEBA ) are provided for each Register to permit independent control of inputting and outputting in either direction of the data flow. The 74LVC543A contains eight D-type Latches with separate inputs and controls for each set. For data flow from pins A to B, for example, the A to B enable input (pin EAB ) must be LOW in order to enter data from pins A0 to A7 or take data from pins B0 to B7, as indicated in the ,Function table,. With pin EAB LOW, a LOW signal on the A to B latch enable input (pin LEAB ) makes the A to B Latches transparent; a subsequent LOW-to-HIGH transition on pin LEAB puts the A data into the Latches where it is stored and the B outputs no longer change with the A inputs. With pins EAB and OEAB both LOW, the 3-state B output Buffers are active and Display the data present at the outputs of the A Latches
