Product Summary

The 74HC4049 is a high-speed Si-gate CMOS device and is pin compatible with the 4049 of the 4000B series. The 74HC4049 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. This feature enables the inverting buffers to be used as logic level translators, which will convert high level logic to low level logic, while operating from a low voltage power supply. For example 5 V logic ( 4000B series) can be converted down to 2 V logic.

Parametrics

74HC4049 absolute maximum ratings: (1)VCC DC supply voltage: -0.5, +7V; (2)VIK DC input voltage range: -0.5, +16V; (3)-IIK DC input diode current: 20mA for VI <-0.5 V; (4)±IOK DC output diode current: 20mA for VO <-0.5 V or VO > VCC +0.5 V; (5)±IO DC output source or sink current standard outputs: 25mA for -0.5 V < VO < VCC +0.5 .
