Part Details:

74LCX540 LOW VOLTAGE CMOS OCTAL BUS BUFFER (3-STATE) WITH 5V TOLERANT INPUTS AND OUTPUTS s 5V TOLERANT INPUTS AND OUTPUTS s HIGH SPEED:tPD = 8.0 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 74LCX540MTR Retention) TSSOP 74LCX540TTR s PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 540 s LATCH-UP PERFORMANCE EXCEEDS The 3 STATE control gate operates as two input 500mA (JESD 17) AND such that if either G1 and G2 are high, all s ESD PERFORMANCE: eight outputs are in the high impedance state. In HBM > 2000V (MIL STD 883 method 3015); order to enhance PC board layout the 74LCX540 MM > 200V offers a pinout having inputs and outputs onopposite sides of the package. DESCRIPTION It has same speed performance at 3.3V than 5V The 74LCX540 is a low voltage CMOS OCTAL AC/ACT family, combined with a lower power BUS BUFFER (INVERTED) fabricated with consumption. sub-micron silicon gate and double-layer metal All inputs and outputs are equipped with wiring C2MOS technology. It is ideal for low power protection circuits against static discharge, giving
