1 TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHC393F/FN/FT TC74VHC393F,TC74VHC393FN,TC74VHC393FT Dual Binary Counter The TC74VHC393 is an advanced high speed CMOS 4-BIT BINARY COUNTER fabricated with silicon gate C 2 MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. It contai 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 traition of the CLOCK pulse. The counter can be reset to 0 (QA to QD = L ) by a high at the CLEAR input regardless of other inputs. An input protection circuit eures that 0 to 5.5 V can be applied to the input pi without regard to the supply voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages. Features High speed: f max = 170 MHz (typ.) at V CC = 5 V Low power dissipation: I CC = 4 μa (max) at Ta = 25 C High noise immunity: V NIH = V NIL = 28% V CC (min) Power down protection is provided on all inputs. Balanced propagation delays: t plh t phl Wide operating voltage range: V CC (opr) = 2 to 5.5 V Low noise: V OLP = 0.8 V (max) Pin and function compatible with 74ALS393 Note: xxxfn (JEDEC SOP) is not available in Japan.
