TC74HC393AFEL,F
TC74HC393AP/AF/AFN TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC393AP,TC74HC393AF,TC74HC393AFN Dual Binary Counter The TC74HC393A is a high speed CMOS 4-BIT BINARY COUNTER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. It contains two independent counter circuits in one package, so that counting or frequency division of eight binary bits can be achieved with one IC. This device changes state on the negative going transition of the CK pulse. The counter can be reset to “0” (QA to QD = “L”) by a high at the CLR input regardless of other inputs. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Note: xxxFN (JEDEC SOP) is not available in Japan. TC74HC393AP TC74HC393AF Features • High speed: fmax = 72 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 • • 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 74LS393 TC74HC393AFN Pin Assignment Weight DIP14-P-300-2.54 SOP14-P-300-1.27A SOL14-P-150-1.27 1 : 0.96 g (typ.) : 0.18 g (typ.) : 0.12 g (typ.) 2007-10-01
