Datasheet
1. General description
2. Features
The 74LVC544A is a high-performance, low-power, low-voltage, Si-gate CMOS device
superior to most advanced CMOS compatible TTL families.
The 74LVC544A is an octal registered inverting transceiver containing two sets of D-type
latches for temporary storage of the data flow in either direction. Separate latch enable
inputs (LEAB and LEBA) and output enable inputs (OEAB and OEBA) are provided for
each register to permit independent control of inputting and outputting in either direction of
the data flow.
The 74LVC544A 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. 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.
