Description

74HC4040D Falling Edge 12-Stage Binary Counter 2V-6V 25mA 98MHz SOIC-16 SMD IC The 74HC4040D is a high-speed, CMOS-level 12-stage binary ripple counter featuring a clock input (CP), twelve parallel outputs (Q0 to Q11), and an overriding asynchronous master reset input (MR) . The internal state of the counter advances sequentially on the HIGH-to-LOW (negative edge) transition of the clock input . Activating the master reset input with a HIGH voltage level clears all counter stages and completely forces all parallel outputs LOW, operating independently of the clock’s state . Each individual counter stage is constructed as a static toggle flip-flop . Built-in clamp diodes on the inputs allow the safe utilization of current-limiting resistors, enabling the chip to cleanly interface with signal voltages that exceed the positive supply line ( V CC ​ ) . Features Wide Supply Voltage Range Low Power Dissipation High Noise Immunity Input Logic Levels Excellent Latch-up Performance Robust ESD Protection Standardization Specifications Parameter / Specification Value / Conditions Unit Package Name SO16 – Supply Voltage (V CC ) 2.0 to 6.0 V Input Voltage (V I ) 0 to V CC V Output Voltage (V O ) 0 to V CC V Ambient Temperature (T amb ) -40 to +125 °C Limiting Values (Absolute Maximums) Supply Voltage Range -0.5 to +7.0 V Input Clamping Current (I IK ) ±20 (for V I < -0.5 V or V I > V CC + 0.5 V) mA Output Clamping Current (I OK ) ±20 (for V O < -0.5 V or V O > V CC + 0.5 V) mA Continuous Output Current (I O ) ±25 mA Supply / Ground Current (I CC / I GND ) ±50 mA Total Power Dissipation (P tot ) 500 (Derates linearly with 12.4 mW/K above 110 °C) mW Storage Temperature (T stg ) -65 to +150 °C Input Capacitance (C I ) 3.5 (Typical) pF Power Dissipation Capacitance (C PD ) 20 (Typical) pF Max Clock Frequency (f max at 2.0 V) 6 (Min) / 27 (Typ) MHz Max Clock Frequency (f max at 4.5 V) 30 (Min) / 82 (Typ) MHz Max Clock Frequency (f max at 6.0 V) 35 (Min) / 98 (Typ) MHz Applications Frequency dividing circuits Time delay circuits Control counters Package Content 1 x 74HC4040D Falling Edge 12-Stage Binary Counter 2V-6V 25mA 98MHz SOIC-16 SMD IC DataSheet 74HC4040D
