FEATURES
* 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 * Direct interface with TTL levels * 8-bit octal transceiver with D-type latch * Back-to-back registers for storage * Separate controls for data flow in each direction * 3-State non-inverting outputs for bus oriented applications * High impedance when VCC = 0V
DESCRIPTION
The 74LVC543A is a high-performance, low-power, low-voltage, Si-gate CMOS device and 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 (LEAB, LEBA) and output enable (OEAB, OEBA) inputs 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 A to B, for example, the A-to-B enable (EAB) input must be LOW in order to enter data from A0-A7 or take data from B0-B7, as indicated in the function table. With EAB LOW, a LOW signal on the A-to-B latch enable (LEAB) input makes the A-to-B latches transparent; a subsequent LOW-to HIGH transition of the LEAB signal puts the A data into the latches where it is stored and the B outputs no longer change with the A inputs. With 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

NOTES: 1. CPD is used to determine the dynamic power dissipation (PD in W) PD = CPD x VCC2 x fi + (CL x VCC2 x fo ) where: fi = input frequency in MHz; CL = output load capacity in pF; fo = output frequency in MHz; VCC = supply voltage in V; (CL x VCC2 x fo ) = sum of the outputs 2. The condition is VI = GND to VCC

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.
