TC74HC374AP
TC74HC374AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC374AP,TC74HC374AF Octal D-Type Flip-Flop with 3-State Output The TC74HC374A 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. These 8-bit D-type flip-flops are controlled by a clock input (CK) and an output enable input ( OE ). When the OE input is high, the eight outputs are in a high impedance state. All inputs are equipped with protection circuits against static discharge or transient excess voltage. TC74HC374AP TC74HC374AF Features • High speed: fmax = 77 MHz (typ.) at VCC = 5 V • Low power dissipation: ICC = 4 μA (max) at Ta = 25°C • High noise immunity: VNIH = VNIL = 28% VCC (min) • Output drive capability: 15 LSTTL loads • • Symmetrical output impedance: |IOH| = IOL = 6 mA (min) ∼ Balanced propagation delays: tpLH − tpHL • Wide operating voltage range: VCC (opr) = 2 to 6 V • Pin and function compatible with 74LS374 Weight DIP20-P-300-2.54A SOP20-P-300-1.27A : 1.30 g (typ.) : 0.22 g (typ.)
