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)
