True 5V CPLD other than PIC/Altera ATF150*?
The ispMACH4A5 family from Lattice Semiconductor. For example: M4A5-32/32-10JNC. These parts are JTAG programmable and range from 32 to 256 macrocells. Plenty of stock on DigiKey, not sure about production. I used them in many designs in the 90s and early 2000s.
