74LVX3245 OCTAL DUAL SUPPLY BUS TRANSCEIVER s HIGH SPEED: tPD = 8ns (MAX.) at TA=25°C VCCA = 3.3V, VCCB = 5.0V s LOW POWER DISSIPATION:ICCA = ICCB = 5µA(MAX.) at TA=25°C s LOW NOISE: VOLP =0.3V (TYP.) at VCC =3.3V s SYMMETRICAL OUTPUT IMPEDANCE: SOP TSSOP |IOH| = IOL = 24mA (MIN) s BALANCED PROPAGATION DELAYS: Table 1: Order Codes tPLH tPHL s OPERATING VOLTAGE RANGE: PACKAGE T & R VCCA(OPR) = 2.7V to 3.6V (1.2V Data Retention) SOP 74LVX3245MTR VCCB(OPR) = 4.5V to 5.5V (1.2V Data Retention) PIN AND FUNCTION COMPATIBLE WITH TSSOP 74LVX3245TTR 74 SERIES 3245 s IMPROVED LATCH-UP IMMUNITY This IC is intended for two-way asynchronouscommunication between data buses and the DESCRIPTION direction of data transmission is determined by The 74LVX3245 is a dual supply low voltage DIR input. The enable input G can be used to CMOS OCTAL BUS TRANSCEIVER fabricated disable the device so that the buses are effectively with sub-micron silicon gate and double-layer isolated. metal wiring C2MOS technology. Designed for use The A-port interfaces with the 3V bus, the B-port as an interface between a 5V bus and a 3.3V bus with the 5V bus. in a mixed 5V/3.3V supply systems, it achieves All inputs are equipped with protection circuits high speed operation while maintaining the CMOS against static discharge, giving them 2KV ESD low power dissipation. immunity and transient excess voltage.
