Counter Dual 4-Bit Binary UP 16-Pin SO Bulk

The 74HCT4520 are high-speed Si-gate CMOS devices and are pin compatible with the “4520” of the “4000B” series. They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT4520 are dual 4-bit internally synchronous binary counters with an active HIGH clock input (nCP0) and an active LOW clock input, buffered outputs from all four bit positions (nQ0 to nQ3) and an active HIGH overriding asynchronous master reset input (nMR). The counter advances on either the LOW-to-HIGH transition of nCP0 if clock input is HIGH or the HIGH-to-LOW transition of clock input if nCP0 is LOW. Either nCP0 or clock input may be used as the clock input to the counter and 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 clock input.
