For example 15 V logic (“4000B series”) can be converted down to 2 V logic. FEATURES • Output capability: standard • ICC category: SSI GENERAL DESCRIPTION The actual input switch level remains related to the VCC and is the same as mentioned in the family characteristics. At the same time each part can be used as a simple inverter without level translation. The 74HC4049 is a high-speed Si-gate CMOS device and is pin compatible with the “4049” of the “4000B” series. It is specified in compliance with JEDEC standard no. 7A. The 74HC4049 provides six inverting buffers with a modified input protection structure, which has no diode connected to VCC. Input voltages of up to 15 V may therefore be used. APPLICATIONS • Converting 15 V logic (“4000B” series) down to 2 V logic.
