TC74HC00AF

The TC74HC00AF is a high speed CMOS 2-input nand  gate fabricated with silicon gate C₂MOS technology.It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.

Features of the TC74HC00AF are:(1)high speed: tpd = 6 ns (typ.) at VCC = 5 V;(2)low power dissipation: Icc = 1 A (max) at Ta = 25°C;(3)high noise immunity: VNIH = VNIL = 28% VCC (min) ;(4)output drive capability: 10 LSTTL loads;(5)symmetrical output impedance: |IOH| = IOL = 4 mA (min);(6)balanced propagation delays: tpLH tpHL;(7)wide operating voltage range: VCC (opr) = 2 to 6 V;(8)pin and function compatible with 74LS00.The internal circuit is composed of 3 stages including buffer output, which provide high noise immunity and stable output. All inputs are equipped with protection circuits against static discharge or transient excess voltage.

The absolute maximum ratings of the TC74HC00AF can be summarized as:(1)supply voltage range Vcc:-0.5 to 7V;(2)DC input voltage Vin:-0.5 to Vcc +0.5V;(3)DC output voltage Vout:-0.5 to Vcc +0.5V;(4)input diode current Iik:±20mA.Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges.The information contained herein is subject to change without notice.TOSHIBA is continually working to improve the quality and reliability of its products. Nevertheless, semiconductor devices in general can malfunction or fail due to their inherent electrical sensitivity and vulnerability to physical stress. The TC74HC00AF is the responsibility of the buyer, when utilizing TOSHIBA products, to comply with the standards of safety in making a safe design for the entire system, and to avoid situations in which a malfunction or failure of such TOSHIBA products could cause loss of human life, bodily injury or damage to property.
