Introduction Summary
FM573 & FM574 Nonvolatile Logic

8-bit Automatic Nonvolatile Latch
- Logic state is preserved in the absence of power
- State is restored automatically on power up
- Output pins driven to correct state almost instantly
- Billions of nonvolatile state changes allowed
- Power supply monitor prevents low-VDD write
- Operates from 2.7V to 5.5V

Operates like conventional CMOS logic
- Transparent (573) or D-Flip-flop (574) operation
- FM573 transparent for C high, latched for C low
- FM574 data is clocked on the rising edge of C
- 33/80 ns data propagation delay (5V/3V)
- 30 MHz/12 MHz maximum frequency (5V/3V)
- Replaces industry standard 74HC573, 74HC574
- 20-pin DIP or SOP
