TOSHIBA TC74VHC393F/FN/FS/FT TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC TC74VHC393F, TC74VHC393FN, TC74VHC393FS, TC74VHC393FT DUAL BINARY COUNTER The TC74VHC393 is an advanced high speed CMOS 4-BIT BINARY COUNTER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent 14 cae 14 ew Bipolar Schottky TTL while maintaining the CMOS low 1 power dissipation. ' It contains two independent counter circuits in one package, F(SOP14-P-300-1.27) FN (SOL14-P-150-1.27) so that counting or frequency division of eight binary bits Weight: 0.189 (TYP.) Weight : 0.129 (TYP.) can be achieved with one IC. This device changes state on the negative going transition of the CLOCK pulse. The counter can be reset to O Ga " att (Q0~Q3=L) by a high at the CLEAR input regardless of other inputs. ' ' An input protection circuit ensures that 0 to 7V can be FS (SSOP 14-P-225-0.65) FT (TSSOP14-P-0044-0.65) applied to the input pins without regard to the supply Weight: 0.07g(TYP.) Weight : 0.069 (TYP.) voltage. This device can be used to interface 5V to 3V PIN ASSIGNMENT systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages. mK 1 ha rT] 14 Vee FEATURES: icLR 2 (J [] 13 2K High Speedsrer--sssssssssssssssssesssesssnsers fuax = 170MHz(typ.) 10A 3 o 7 12 2CLR at Vcc = 5V + Low Power Dissipation +--+ loc = 4uA(Max.) at Ta = 25C 198 4[ 1] 11 2QA e High Noise Immunity--------0-+-+-+ Vii = Vit = 28% Voc (Min.) ec 5 J r] 10 2QB e Power Down Protection is provided on all inputs. 1QD 6 e Balanced Propagation Delays---- tpLy=tpHL Q q 9 2ac + Wide Operating Voltage Range-- Vcc (opr) = 2V~5.5V GND 7 Ms 29D @ LOW Noise vevertssesereresssecestscenseesseees Voip = 0.8V (Max.) e Pin and Function Compatible with 74ALS393 {TOP VIEW) 1EC LOGIC SYMBOL 1QA 1QB 1Q 1QD 2QA 2QB 2QC 2QD 961001EBA2 @ TOSHIBA is continually working to improve the quality and the reliability of its products.
