The 74HCT4020PW-Q100 is a 14-stage binary ripple counter designed for automotive applications, qualified to AEC-Q100 (Grade 1). It features a clock input (CP) that triggers on the HIGH-to-LOW transition and an asynchronous master reset input (MR) that clears all counter stages. The device provides 12 buffered parallel outputs (Q0, Q3 to Q13) and operates over a wide supply voltage range of 2.0 V to 6.0 V. It is specified for temperatures ranging from -40 ¬8C to +125 ¬8C, making it suitable for harsh environments. The counter exhibits low power dissipation and high noise immunity, with latch-up performance exceeding 100 mA per JESD 78 Class II Level B. The product also includes ESD protection exceeding 2000 V for HBM and is available in multiple package options, including TSSOP16. Applications include frequency dividing circuits, time delay circuits, and control counters.
The 74HC4020-Q100; 74HCT4020-Q100 is a 14-stage binary ripple counter with a clock input (CP), an overriding asynchronous master reset input (MR) and 12 buffered parallel outputs (Q0, and Q3 to Q13). The counter advances on the HIGH-to-LOW transition of CP. A HIGH on MR clears all counter stages and forces all outputs LOW, independent of the state of CP. Each counter stage is a static toggle flip-flop. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.
