DESCRIPTION

The 74LVX4245 is a dual supply low voltage CMOS OCTAL BUS TRANSCEIVER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. Designed for use as an interface between a 5V bus and a 3.3V bus in a mixed 5V/3.3V supply systems, it achieves high speed operation while maintaining the CMOS low power dissipation.

■ HIGH SPEED: tPD = 8.5 ns (MAX.) at VCCA=5.0V VCCB = 3.3V

■ LOW POWER DISSIPATION: ICCA = ICCB =5µA(MAX.) at TA=25°C

■ LOW NOISE: VOLP =0.3V (TYP.) at VCCA=5.5V VCCB=3.3V

■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 24mA (MIN)

■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL

■ OPERATING VOLTAGE RANGE: VCCA(OPR) = 4.5V to 5.5V (1.2V Data Retention) VCCB(OPR) = 2.7V to 3.6V (1.2V Data Retention) PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 4245

■ IMPROVED LATCH-UP IMMUNITY
