FAST CMOS

OCTAL LATCHED

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
