DESCRIPTION:
The FCT543 is a non-inverting octal transceiver built using an ad-
vanced dual metal CMOS technology. These devices contain two sets of
eight D-type latches with separate input and output controls for each set. For
data flow from A to B, for example, the A-to-B Enable (CEAB) input must be
low in order to enter data from A0–A7 or to take data from B0–B7, as indicated
in the Function Table. With CEAB 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 latches in the storage
mode and their outputs no longer change with the A inputs. With CEAB and
OEAB both low, the 3-state B output buffers are active and reflect the data
present at the output of the A latches. Control of data from B to A is similar,
but uses the CEBA, LEBA and OEBA inputs.

NOTES:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 5.0V, +25°C ambient.
3. Per TTL driven input (VIN = 3.4V); all other inputs at VCC or GND.
4. This parameter is not directly testable, but is derived for use in Total Power Supply calculations.
5. Values for these conditions are examples of the ICC formula. These limits are guaranteed but not tested.
6. IC = IQUIESCENT + IINPUTS + IDYNAMIC
IC = ICC + ICC DHNT + ICCD (fCP/2 + fiNi)
ICC = Quiescent Current
ICC = Power Supply Current for a TTL High Input (VIN = 3.4V)
DH = Duty Cycle for TTL Inputs High
NT = Number of TTL Inputs at DH
ICCD = Dynamic Current Caused by an Output Transition Pair (HLH or LHL)
fCP = Clock Frequency for Register Devices (Zero for Non-Register Devices)
fi = Input Frequency
Ni = Number of Inputs at fi
All currents are in milliamps and all frequencies are in megahertz.
