TC74HCT574AF

TC74HCT574AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HCT574AP, TC74HCT574AF Octal D-Type Flip-Flop with 3-State Output The TC74HCT574A is a high speed CMOS OCTAL FLIP-FLOP with 3-STATE OUTPUT fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. Its inputs are compatible with TTL, NMOS, and CMOS output voltage levels. Its 8-bit D-type flip-flops is controlled by a clock input (CK) and an output enable input ( OE ). All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features High speed: fmax = 62 MHz (typ.) at VCC = 5 V Low power dissipation: ICC = 4 μA (max) at Ta = 25°C Compatible with TTL outputs: VIL = 0.8 V (min) VIH = 2.0 V (max) Output drive capability: 15 LSTTL loads Symmetrical output impedance: |IOH| = IOL = 6 mA (min) Balanced propagation delays: tpLH ∼− tpHL Pin and function compatible with 74LS574 Pin Assignment TC74HCT574AP TC74HCT574AF Weight DIP20-P-300-2.54A SOP20-P-300-1.27A : 1.30 g (typ.) : 0.22 g (typ.)
