DESCRIPTION
The 74VCX1632245 is a dual supply low voltage CMOS 16-BIT BUS TRANSCEIVER fabricated with sub-micron silicon gate and five-layer metal wiring C2MOS technology. Designed for use as an interface between a 3.3V bus and a 2.5V or 1.8V bus in a mixed 3.3V/1.8V,3.3V/2.5V and 2.5V/1.8V supply systems, it achieves high speed operation while maintaining the CMOS low power dissipation.

■ HIGH SPEED: tPD = 4.4ns (MAX.) at TA=85°C
   VCCA = 3.0V VCCB = 2.3V
■ LOW POWER DISSIPATION:
   ICCA = ICCB = 20µA(MAX.) at TA=85°C
■ SYMMETRICAL OUTPUT IMPEDANCE:
   |IOHA| = IOLA = 8mA MIN at
   VCCA = 3.0V VCCB = 1.65V or 2.3V
   |IOHA| = IOLA = 18mA MIN at
   VCCA = 2.3V VCCB = 1.65V)
■ BALANCED PROPAGATION DELAYS:
   tPLH ≅ tPHL
■ POWER DOWN PROTECTION ON INPUTS
   AND OUTPUTS
■ 26ΩSERIES RESISTOR ON A SIDE OUTPUTS
