■ 제품사양

Logic Function = AND
장착형태 = Surface Mount Number of Elements = 2 Number of Inputs per Gate = 4
패키지 = SOIC
핀수 = 14 Logic Family = 74HC Maximum Operating Supply Voltage = 6 V Maximum High Level Output Current = -5.2mA Maximum Propagation Delay Time @ Maximum CL = 125 ns @ 50 pF Minimum Operating Supply Voltage = 2 V Maximum Low Level Output Current = 5.2mA
높이 = 1.38mm The 74HC21D is a high speed CMOS 4-INPUT AND GATE fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The internal circuit is composed of 4 stages including buffer an output, which provide high noise immunity and stable output. All inputs are equipped with protection circuits against static discharge or transient excess voltageHigh speed: tpd = 10 ns (typ.) at VCC = 5 V Low power dissipation: ICC = 1.0 μA (max) Ta = 25 ??Balanced propagation delays: tPLH ??tPHL Wide operating voltage range: VCC(opr) = 2.0 to 6.0 V
