The 74HC/HCT4518 are high-speed Si-gate CMOS devices and are pin compatible with the “4518” of the “4000B” series. They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT4518 are dual 4-bit internally synchronous BCD counters with an active HIGH clock input (nCP0) and an active LOW clock input (nCP1), buffered outputs from all four bit pos.
• Output capability: standard
• ICC category: MSI
GENERAL DESCRIPTION
The 74HC/HCT4518 are high-speed Si-gate CMOS devices and are pin compatible with the “4518” of the “4000B” series. They are specified in compliance with JEDEC standard no. 7A.
The 74HC/HCT4518 are dual 4-bit internally synchronous BCD counters with an active HIGH clock input (nCP0) and an active LOW clock input (nCP1), 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 nCP1 is HIGH.
The 74HC/HCT4518 are high-speed Si-gate CMOS devices and are pin compatible with the “4518” of the “4000B” series. They .
