1. General description
The 74HC4520-Q100; 74HCT4520-Q100 are dual 4-bit internally synchronous binary counters
with two clock inputs (nCP0 and nCP1). They have buffered outputs from all 4 bit positions
(nQ0 to nQ3), and an asynchronous master reset input (nMR). The counter advances on either
the LOW-to-HIGH transition of nCP0 when nCP1 is HIGH. It also advances on the HIGH-to-LOW
transition of nCP1 if nCP0 is LOW. Either nCP0 or nCP1 may be used as the clock input to the
counter. The other clock input may be used as a clock enable input. A HIGH on nMR resets the
counter (nQ0 to nQ3 = LOW) independent of nCP0 and nCP1. Inputs include clamp diodes. It
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.
