TC74HC590AF 8-Bit Binary Counter/Register

TC74HC590AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC590AP, TC74HC590AF 8-Bit Binary Counter/Register with 3-State Outputs The TC74HC590A is a high speed CMOS 8-BIT COUNTER/REGISTER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to epuivalent LSTTL while maintaining the CMOS low power d.

Features

• High speed: fmax = 62 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 for QA to QH 10 LSTTL loads for RCO
• Symmetrical output impedance: |IOH| = IOL = 6 mA (min) For QA to QH |IOH| = IOL = 4 mA (min) For RCO
• Balanced propagation delays: tpLH ≈ tpHL
• Wide operating voltage range: VCC (opr) = 2 to 6 V
• Pin and function compatible with 74LS590 Pin Assignment TC74HC590AP TC74HC590AF Weight DIP16-P-300-2.54A SOP16-P-300-1.27A : 1.00 g (typ.) : 0.18 g (typ.) Start of.
