■ 제품사양

Logic Family = 74HC
장착형태 = Surface Mount
패키지 = SOIC
핀수 = 20 Maximum High Level Output Current = -7.8mA Maximum Low Level Output Current = 7.8mA Maximum Propagation Delay Time @ Maximum CL = 165 ns @ 150 pF Maximum Operating Supply Voltage = 6 V
높이 = 2.25mm The 74HC540D/74HC541D are high speed CMOS OCTAL BUS BUFFERs fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The 74HC540D is an inverting type, and the 74HC541D is a non-inverting type. When either G1 or G2 are high, the terminal outputs are in the high-impedance state. All inputs are equipped with protection circuits against static discharge or transient excess voltageHigh speed: tpd = 10 ns (typ.) at VCC = 6.0 V Low power dissipation: ICC = 4.0 μA (max) at Ta = 25 ??Balanced propagation delays: tPLH ??tPHL Wide operating voltage range: VCC(opr) = 2.0 V to 6.0 V
