Product Summary
The TC74HC02AF is a high speed CMOS monostable multivibrator fabricated with silicon gate C2MOS technology. The TC74HC02AF achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. There are two trigger inputs, A input (negative edge), and B input (positive edge). These inputs are valid for a slow rise/fall time signal (tr = tf = 1 s) as they are schmitt trigger inputs. The TC74HC02AF may also be triggered by using CLR input (positive edge).
Parametrics
TC74HC02AF absolute maximum ratings: (1)Supply voltage range:-0.5 to 7V; (2)DC input voltage:-0.5 to VCC + 0.5V; (3)DC output voltage:-0.5 to VCC + 0.5V; (4)Input diode current:±20mA; (5)Output diode current:±20mA; (6)DC output current:±25mA; (7)DC VCC/ground current:±50mA; (8)Power dissipation:180mW; (9)Storage temperature:-65℃ to 150℃.
Features
TC74HC02AF features: (1)High speed: tpd = 25 ns (typ.) at VCC = 5 V; (2)Low power dissipation: Standby state: ICC = 4 μA (max) at Ta = 25℃, Active state: ICC = 700 μA (max) at Ta = 25℃; (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 74LS123.
