metal CMOS technology. The FCT2245T is designed for asynchronous

two-waycommunicationbetweendatabuses. Thetransmit/receive(T/R)

inputdetermines the directionofdata flowthroughthe bidirectionaltrans-

ceiver. Transmit (active high) enables data from A ports to B ports, and

receive (active low)fromBports toAports. The outputenable (OE)input,

whenhigh,disables bothAandBports byplacingtheminhighZcondition.

FCT2245T parts are plug-in replacements for FCT245T parts.

– VOL = 0.3V (typ.)

• Meets or exceeds JEDEC standard 18 specifications

• Resistor outputs -15mA IOH, 12mA IOL

• Reduced system switching noise

• Available in SOIC and QSOP packages
