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)
■ PIN AND FUNCTION COMPATIBLE WITH
   74 SERIES 16245
■ LATCH-UP PERFORMANCE EXCEEDS
   500mA (JESD 17)
■ ESD PERFORMANCE:
   HBM > 2000V (MIL STD 883 method 3015);
   MM > 200V
