DRIVERS

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:

TheIDToctalbuffer/linedriversarebuiltusinganadvanced

dual metal CMOS technology. The FCT240T/FCT2240T and

FCT244T/FCT2244Taredesignedtobeemployedasmemory

and address drivers, clock drivers and bus-oriented transmit-

ter/receivers which provide improved board density.

The FCT540T and FCT541T/FCT2541T are similar in

functiontotheFCT240T/FCT2240TandFCT244T/FCT2244T,

respectively, except that the inputs and outputs are on oppo-

site sides of the package. This pinout arrangement makes

these devices especially useful as output ports for micropro-

cessorsandasbackplanedrivers, allowingeaseoflayoutand

greater board density.

TheFCT2240T, FCT2244TandFCT2541Thavebalanced

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 resis-

tors. FCT2xxxT parts are plug-in replacements for FCTxxxT

parts.

– 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 FCT240T/FCT244T/FCT540T/FCT541T:

– Std., A, C and D speed grades

– High drive outputs (-15mA IOH, 64mA IOL)

• Features for FCT2240T/FCT2244T/FCT2541T:

– Std., A and C speed grades

– Resistor outputs (-15mA IOH, 12mA IOL Com.)

(-12mA IOH, 12mA IOL Mil.)

– Reduced system switching noise
