FAST CMOS OCTAL LATCHED TRANSCEIVER MILITARY AND COMMERCIAL TEMPERATURE RANGES JANUARY 1995 ©1995 Integrated Device Technology, Inc. 6.17 DSC-4203/5 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 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. 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. 1 FEATURES: • Common features: – Low input and output leakage ≤1µA (max.) – CMOS power levels – True TTL input and output compatibility – VOH = 3.3V (typ.) – 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.)
