Oh, but only the 9500 series is a 5V part. The 9500 XL is 5
V tolerant, but needs 3.3 V supply.

The Xilinx 9500 series of CPLDs are not low-power, by any
means. They have a formula in the data sheet and a power
calculator program, that are both WRONG! They
underestimate power by a factor of 3!! I reported this to
them, and they said I was right, but they were not going
to fix the documentation! Sheesh!
(The internal architecture is 36-input diode gates with
pull-up resistors. You have two choices of resistor,
low-power and fast.)
The Xilinx CoolRunner II is quite low power, basically a
CMOS FPGA architecture.

I think a well chosen hearing aid tube can outperform a
classic (not
L or LS) 7400 series IC.
This application sound like a perfect candidate for a
CPLD.
