Part Details:

74VHC240 Octal Buff April 2007 74VHC240 tm Octal Buffer/Line Driver with 3-STATE Outputs Features General Description er/Line Driver with 3-ST High Speed: tPD = 3.6ns (typ) at TA = 25°C The VHC240 is an advanced high speed CMOS octal Low power dissipation: I bus buffer fabricated with silicon gate CMOS technology. CC = 4µA (max) @ TA = 25°C High noise immunity: V It achieves high speed operation similar to equivalent NIH = VNIL = 28% VCC (min.) Bipolar Schottky TTL while maintaining the CMOS low Power down protection is provided on all inputs power dissipation. The VHC240 is an inverting 3-STATE Low noise: VOLP = 0.9V (max.) buffer having two active-LOW output enables. This Pin and function compatible with 74HC240 device is designed to drive buslines or buffer memoryaddress registers. An input protection circuit ensures that 0V to 7V can beapplied to the input pins without regard to the supplyvoltage. This device can be used to interface 5V to 3Vsystems and two supply systems such as battery ATE Outputs backup. This circuit prevents device destruction due tomismatched supply and input voltages.
