TC74HC592AF

TC74HC592AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC592AP, TC74HC592AF 8-Bit Binary Counter with Input Register The TC74HC592A is high speed CMOS 8-BIT REGISTER COUNTER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The internal counter counts at positive edge of Counter Clock (CCK) when Counter Clock Enable ( CCKEN ) is held “L” level. If Counter clear ( CCLR ) is held “L”, the internal counter is cleared asynchronously to clock. Input A to H are loaded to register at positive edge of Register Clock (RCK), and the register outputs are loaded to Counter when Counter Load ( CLOAD ) is held “L” level. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features High speed: fmax = 35 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: 10 LSTTL loads for QA to QH Symmetrical output impedance: |IOH| = IOL = 4 mA (min) Balanced propagation delays: tpLH ∼− tpHL Wide operating voltage range: VCC (opr) = 2 to 6 V Pin and function compatible with 74LS592 Pin Assignment TC74HC592AP TC74HC592AF Weight DIP16-P-300-2.54A: SOP16-P-300-1.27A: 1.00 g (typ.) 0.18 g (typ.)
