| The 74VHC393FT 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 Bipolar Schottky TTL 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. An input protection circuit ensures that 0 to 5.5 V can be applied to the input pins 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 voltagesWide operating temperature range: Topr = -40 to 125 High speed: fMAX = 165 MHz (typ.) at VCC = 5.0 V Low power dissipation: ICC = 4.0 μA (max) at Ta = 25 High noise immunity: VNIH = VNIL = 28% VCC (min) Power-down protection is provided on all inputs. Balanced propagation delays: tPLH ≈ tPHL Wide operating voltage range: VCC(opr) = 2.0 V to 5.5 V Low noise: VOLP = 0.8 V (max) Pin and function compatible with the 74 series (74AC/HC/AHC etc.) 393 type More information: | | Package Type: | TSSOP | Logic Function: | Counter | Logic Family: | 74VHC | Mounting Type: | Surface Mount | Counter Type: | Binary | Number of Elements: | 1 | Pin Count: | 14 | Minimum Operating Supply Voltage: | 2 V | Maximum Operating Supply Voltage: | 5.5 V | Dimensions: | 5.02 x 4.4 x 1mm | Automotive Standard: | AEC-Q100 | Direction Type: | Uni-Directional | Maximum Operating Temperature: | 125 °C | Minimum Operating Temperature: | -40 °C | Height: | 1mm |
