74HC4520; 74HCT4520 Dual 4-bit synchronous binary counter Rev. 5 — 14 February 2019 Product data sheet 1. General description 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. It enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. 2. Features and benefits • • • • Complies with JEDEC standard no. 7A Input levels: • For 74HC4520: CMOS level • For 74HCT4520: TTL level ESD protection: • HBM JESD22-A114F exceeds 2000 V • MM JESD22-A115-A exceeds 200 V Specified from -40 °C to +85 °C and -40 °C to +125 °C 3.
