The supply rails consist of Static Drive (I /I ) OH OL V , which is the higher potential rail operating at 2.3V to CCB ±24 mA @ 3.0V V CC 3.6V and V , which is the lower potential rail operating at CCA 1.65V to 2.7V. (V must be less than or equal to V ±18 mA @ 2.3V V CCA CCB CC for proper device operation.) This dual supply design ±6 mA @ 1.65V V CC allows for translation from 1.8V to 2.5V busses to busses at Uses patented noise/EMI reduction circuitry a higher potential, up to 3.3V. Functionally compatible with 74 series 16245 The Transmit/Receive (T/R) input determines the direction Latchup performance exceeds 300 mA of data flow. Transmit (active-HIGH) enables data from A Ports to B Ports. Receive (active-LOW) enables data fromESD performance: B Ports to A Ports. The Output Enable (OE) input, when Human Body Model >2000V HIGH, disables both A and B Ports by placing them in a Machine model >200V High-Z condition. The A Port interfaces with the lower volt- Also packaged in plastic Fine-Pitch Ball Grid Array age bus (1.8V − 2.5V). The B Port interfaces with the (FBGA) higher voltage bus (2.7V − 3.3V). Also the VCX164245 is designed so that the control pins (T/R , OE ) are supplied n n by V . CCB Note 1: To ensure the high impedance state during power up or power The 74VCX164245 is suitable for mixed voltage applica- down, OE should be tied to V through a pull up resistor. The minimum n CCB tions such as notebook computers using a 1.8V CPU and value of the resistor is determined by the current sourcing capability of the 3.3V peripheral components. It is fabricated with an driver. Advanced CMOS technology to achieve high speed opera- tion while maintaining low CMOS power dissipation.
