74HC393D CMOS Digital Integrated Circuits Silicon Monolithic 74HC393D 1. Functional Description Dual Binary Counter 2. General The 74HC393D 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 to0 (QA to QD =) 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. 3. Features (1) Wide operating temperature range: T = -40 to 125 (Note 1) opr (2) High speed: f = 72 MHz (typ.) at V = 5 V MAX CC (3) Low power dissipation: I = 4.0 A (max) at T = 25 CC a (4) Balanced propagation delays: t t PLH PHL (5) Wide operating voltage range: V = 2.0 V to 6.0 V CC(opr) Note 1: Operating Range spec of T = -40 to 125 is applicable only for the products which manufactured after opr July 2020. 4.
