TRANSCEIVER  
Integrated Device Technology, Inc.  
FEATURES:  
• Common features:  
– Low input and output leakage 1µA (max.)  
– CMOS power levels  
– True TTL input and output compatibility  
– VOH = 3.3V (typ.)  
DESCRIPTION:  
The FCT543T/FCT2543T is a non-inverting octal trans-  
ceiver built using an advanced dual metal CMOS technology.  
This device contains two sets of eight D-type latches with  
separate input and output controls for each set. For data flow  
fromAtoB, forexample, theA-to-BEnable(CEAB)inputmust  
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.  
– VOL = 0.3V (typ.)  
– Meets or exceeds JEDEC standard 18 specifications  
– Product available in Radiation Tolerant and Radiation  
Enhanced versions  
– Military product compliant to MIL-STD-883, Class B  
and DESC listed (dual marked)  
– Available in DIP, SOIC, SSOP, QSOP, CERPACK  
and LCC packages  
• Features for FCT543T:  
– Std., A, C and D speed grades  
– High drive outputs (-15mA IOH, 64mA IOL)  
– Power off disable outputs permit “live insertion”  
• Features for FCT2543T:  
– Std., A, and C speed grades  
– Resistor outputs (-15mA IOH, 12mA IOL Com.)  
(-12mA IOH, 12mA IOL Mil.)  
The FCT2543T has balanced output drive with current  
limiting resistors. This offers low ground bounce, minimal  
undershoot and controlled output fall times-reducing the need  
for external series terminating resistors. FCT2xxxT parts are  
plug-in replacements for FCTxxxT parts.  
– Reduced system switching noise
