Part Details:

74LCX245 LOW VOLTAGE CMOS OCTAL BUS TRANSCEIVER (3-STATE) WITH 5V TOLERANT INPUTS AND OUTPUTS s 5V TOLERANT INPUTS AND OUTPUTS s HIGH SPEED:tPD = 7.0 ns (MAX.) at VCC = 3V s POWER DOWN PROTECTION ON INPUTS AND OUTPUTS s SYMMETRICAL OUTPUT IMPEDANCE:|I SOP TSSOP OH| = IOL = 24mA (MIN) at VCC = 3V s PCI BUS LEVELS GUARANTEED AT 24 mA s BALANCED PROPAGATION DELAYS: Table 1: Order Codes tPLH tPHL s OPERATING VOLTAGE RANGE: PACKAGE T & R VCC(OPR) = 2.0V to 3.6V (1.5V Data SOP 74LCX245MTR Retention) TSSOP 74LCX245TTR s PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 245 s LATCH-UP PERFORMANCE EXCEEDS It has same speed performance at 3.3V than 5V 500mA (JESD 17) AC/ACT family, combined with a lower power s ESD PERFORMANCE: consumption. HBM > 2000V (MIL STD 883 method 3015); This IC is intended for two way asynchronous MM > 200V communication between data buses; the directionof data transmission is determined by DIR input. DESCRIPTION The enable input G can be used to disable the The 74LCX245 is a low voltage CMOS OCTAL device so that the buses are effectively isolated. BUS TRANSCEIVER (3-STATE) fabricated with All inputs and outputs are equipped with sub-micron silicon gate and double-layer metal protection circuits against static discharge, giving wiring C2MOS technology. It is ideal for low power them 2KV ESD immunity and transient excess
