Logic family for 3.3 V microcontroller interface
The 74LS family is, by definition, 5V only. If you're working with 3.3V parts, ignore it.

The 74HC family is 3.3V compatible. The 74HC154 may be suitable for your needs. However, note that it is only available in surface-mount packages; the DIP 74HC154 was discontinued by most manufacturers some time ago.

Another option is a pair of 74HC138 3-to-8 decoders. These parts have both active-high and active-low enable pins, so they can be combined to emulate a 4-to-16 decoder.

If the speeds of the 74HC family aren't sufficient for your needs, you can step up to the 74AHC family, which is also 3.3V only. There is no 74AHC version of the '154, but the '138 is available.
