And if you don't care how much juice it sucks.
Yes. I had quite a wide selection of units that pulled some tens of
mW, but trying to sort through and find a few with something much more
reasonable was difficult -- as in, very frustrating.
In the meantime, there is the HA7210 that can help for lower power.
Also, I've found that where you already have an external oscillator
available, in some cases you can drive the OUTPUT side of the two-pin
xtal class-A oscillators and cause the internal inverter to find a
stable, quiescent state where it doesn't oscillate at all and thus
draw power. That alone can cut power consumption in half over what
would happen when you try and drive the INPUT side where the internal
inverter just ticks away and sucks power. Those inverters can be
surprising in what they suck down when they invert, it seems. Of
course, you have to have a case where the output side does in some way
drive the internal chip. Some of the PICs are like that, for example,
and drive quite well from the output pin at substantially lower power.
