FEATURES
DESCRIPTION
The 74LVC543A is a high–performance, low–power, low–voltage,
Si–gate CMOS device and superior to most advanced CMOS
compatible TTL families.
• 5-volt tolerant inputs/outputs, for interfacing with 5-volt logic
• Supply voltage range of 1.2V to 3.6V
• Complies with JEDEC standard no. 8–1A
• CMOS low power consumption
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 (LE , LE ) and output
AB
BA
enable (OE , OE ) inputs are provided for each register to permit
independent control of inputting and outputting in either direction of
the data flow.
• Direct interface with TTL levels
AB
BA
• 8-bit octal transceiver with D-type latch
• Back-to-back registers for storage
The 74LVC543A contains eight D–type latches, with separate inputs
and controls for each set. For data flow from A to B, for example, the
• Separate controls for data flow in each direction
• 3-State non-inverting outputs for bus oriented applications
A–to–B enable (E ) input must be LOW in order to enter data from
AB
A –A or take data from B –B , as indicated in the function table.

input makes the A–to–B latches transparent; a subsequent LOW–to
HIGH transition of the LE signal puts the A data into the latches

where it is stored and the B outputs no longer change with the A
inputs. With E and OE both low, the 3–state B output buffers
AB

are active and display the data present at the outputs of the A
latches

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
