74LCX05 LOW VOLTAGE HEX INVERTER (OPEN DRAIN) WITH 5V TOLERANT INPUTS ■ ■ ■ ■ ■ ■ ■ ■ 5V TOLERANT INPUTS HIGH SPEED: tPD = 5.2 ns (MAX.) at VCC = 3V POWER-DOWN PROTECTION ON INPUTS AND OUTPUTS PCI BUS LEVELS GUARANTEED AT 24mA OPERATING VOLTAGE RANGE: VCC (OPR) = 2.0V to 3.6V (1.5V Data Retention) PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 05 LATCH-UP PERFORMANCE EXCEEDS 500mA ESD PERFORMANCE: HBM >2000V; MM > 200V DESCRIPTION The 74LCX05 is an advanced high-speed CMOS OPEN DRAIN HEX INVERTER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power and high speed 3.3V applications; it can be interfaced to 5V signal environment for inputs. The internal circuit is composed of 3 stages M (Micro Package) T (TSSOP Package) ORDER CODES : 74LCX05M 74LCX05T including buffer output, which provides high noise immunity and stable output. It has same speed performance at 3.3V than 5V, AC/ACT family, combined with a lower power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
