74HC4520D-Q100

Dual 4-bit synchronous binary counter; ? Automotive product qualification in accordance with AEC-Q100 (Grade 1)? Specified from -40 °C to +85 °C and from -40 °C to +125 °C\n\n? Complies with JEDEC standard no. 7A\n? Input levels:? For 74HC4520-Q100: CMOS level\n? For 74HCT4520-Q100: TTL level\n\n? ESD protection:? MIL-STD-883, method 3015 exceeds 2000 V\n? HBM JESD22-A114F exceeds 2000 V\n? MM JESD22-A115-A exceeds 200 V (C = 200 pF, R = 0 Ω)\n\n;

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 (nQ0tonQ3), 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 (nQ0tonQ3=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.\n This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.\n

The 74HC4520; 74HCT4520 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 the LOW-to-HIGH transition of nCP0 when nCP1 is HIGH. It also advances on the HIGH-to-LOW transition of nCP1 when 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.
