The Xilinx 9500 series of CPLDs are not low-power, by any

said I was right, but they were not going to fix the

(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.
