74LVX4245 OCTAL DUAL SUPPLY BUS TRANSCEIVER s HIGH SPEED: tPD = 8.5 ns (MAX.) at VCCA=5.0V VCCB = 3.3V s LOW POWER DISSIPATION:ICCA = ICCB =5µA(MAX.) at TA=25°C s LOW NOISE: VOLP =0.3V (TYP.) at VCCA=5.5V 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 74LVX4245MTR CCA(OPR) = 4.5V to 5.5V (1.2V Data Retention) V TSSOP 74LVX4245TTR CCB(OPR) = 2.7V to 3.6V (1.2V Data Retention) PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 4245 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 74LVX4245 is a dual supply low voltage disable the device so that the buses are effectively CMOS OCTAL BUS TRANSCEIVER fabricated isolated. with sub-micron silicon gate and double-layer The A-port interfaces with the 5V bus, the B-port metal wiring C2MOS technology. Designed for use with the 3.3V bus. as an interface between a 5V bus and a 3.3V bus All inputs are equipped with protection circuits in a mixed 5V/3.3V supply systems, it achieves against static discharge, giving them 2KV ESD high speed operation while maintaining the CMOS immunity and transient excess voltage. low power dissipation.
