DESCRIPTION
The 74LVXC3245 is a dual supply 8 bit configurable 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 3.3V bus and a 3.3V to 5V bus in a mixed 3.3V/5V supply systems, it achieves high speed operation while maintaining the CMOS low power dissipation.
This IC is intended for two-way asynchronous communication between data buses and the direction of data transmission is determined by DIR input. The enable input G can be used to disable the device so that the buses are effectively isolated.
The A-port interfaces with the 3V bus, the B-port with the 5V bus.
All inputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.

■ HIGH SPEED:
   tPD = 8ns (MAX.) at TA=25°C
   VCCA = 3.3V, VCCB = 5.0V
■ LOW POWER DISSIPATION:
   ICCA = ICCB = 5µA(MAX.) at TA=25°C
■ LOW NOISE: VOLP =0.3V (TYP.) at VCCA=3.3V
■ SYMMETRICAL OUTPUT IMPEDANCE:
   |IOH| = IOL = 24mA (MIN)
■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL
■ OPERATING VOLTAGE RANGE:
   VCCA(OPR) = 2.7V to 3.6V (1.2V Data Retention)
   VCCB(OPR) = 2.7V to 5.5V (1.2V Data Retention)
   PIN AND FUNCTION COMPATIBLE WITH
   74 SERIES C3245
■ IMPROVED LATCH-UP IMMUNITY
