74LVXC4245 OCTAL DUAL SUPPLY BUS TRANSCEIVER s HIGH SPEED: tPD = 6.5ns (MAX.) at VCCA = 5.0V, VCCB = 5.0V s LOW POWER DISSIPATION:ICCA = ICCB = 5µA(MAX.) at TA=25°C s LOW NOISE: VOLP =0.3V (TYP.) at VCCA=5.0V VCCB =3.3V SOP TSSOP s SYMMETRICAL OUTPUT IMPEDANCE:|IOH| = IOL = 24mA (MIN) Table 1: Order Codes s BALANCED PROPAGATION DELAYS:tPLH tPHL PACKAGE T & R s OPERATING VOLTAGE RANGE:V SOP 74LVXC4245MTR CCA(OPR) = 4.5V to 5.5V (1.2V Data Retention) V TSSOP 74LVXC4245TTR CCB(OPR) = 2.7V to 5.5V (1.2V Data Retention) PIN AND FUNCTION COMPATIBLE WITH 74 SERIES C4245 This IC is intended for two-way asynchronous s IMPROVED LATCH-UP IMMUNITY communication between data buses and thedirection of data transmission is determined by DESCRIPTION DIR input. The enable input G can be used to The 74LVXC4245 is a dual supply 8 bit disable the device so that the buses are effectively configurable low voltage CMOS OCTAL BUS isolated. TRANSCEIVER fabricated with sub-micron silicon The A-port interfaces with the 5V bus, the B-port gate and double-layer metal wiring C2MOS with the 3.3V to 5V bus. technology. Designed for use as an interface All inputs are equipped with protection circuits between a 5V bus and a 3.3V to 5V bus in a mixed against static discharge, giving them 2KV ESD 5V/3.3V supply systems, it achieves high speed immunity and transient excess voltage. operation while maintaining the CMOS low powerdissipation.
