DESCRIPTION

The 74VCX163245 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 = 12mA MIN at

VCCA = 3.0V VCCB = 1.65V or 2.3V

|IOHA| = IOLA = 8mA MIN at

VCCA = 2.3V VCCB = 1.65V)

■ BALANCED PROPAGATION DELAYS:

tPLH ? tPHL

■ POWER DOWN PROTECTION ON INPUTS

AND OUTPUTS

■ OPERATING VOLTAGE RANGE:

VCCA(OPR)=2.3Vto3.6V(1.2VDataRetention)

VCCB(OPR)=1.65Vto2.7V(1.2VDataRetention)
