    Features

    AEC-Q100 (Rev. H) (Note 1)

    Wide operating temperature range: Topr = -40 to 125 

    High speed: fMAX = 170 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.


    Applications

    1. Digital Frequency Division & Counting Systems
    With its dual 4-bit binary ripple counter structure and asynchronous reset function, it is suitable for:

    • Clock frequency division circuits (dividing high-frequency clocks into low-frequency control signals)

    • Event counters (industrial production line counting, speed measurement)

    • Base frequency generation for timers (enabling precise timing control with MCUs)

    2. Consumer Electronics & Portable Devices
    2-5.5V wide voltage support and low-power characteristics make it ideal for:

    • Smart home devices for operational state cycle counting (e.g., timed switch control)

    • Toy electronics for light/sound effect sequence generation (LED flashing pattern control)

    • Remote controls for button press statistics and low-power standby counting

    3. Industrial Control & Automation
    High noise immunity and 8mA output drive support harsh environments:

    • PLC systems for pulse signal frequency division and step control

    • Motor encoder signal frequency division (reducing MCU counting load)

    • Sensor signal accumulation counting (flow sensors, displacement detection)

    4. Communication & Interface Design
    5.5V tolerant inputs support mixed-voltage systems:

    • UART/I2C interfaces for baud rate frequency division generation

    • Data acquisition systems for sampling frequency分级 control

    • Display devices for scan frequency division (LED matrix refresh control)


    Description

    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 voltages.
