Key Features

  • High-performance, high-density replacement for TTL, 74HC, and custom logic.
  • 32 macrocells, 64 expander product terms in one LAB.
  • 8 dedicated inputs, 16 I/O pins.
  • 0.8-micron double-metal CMOS EPROM technology.
  • 28-pin, 300-mil DIP, cerDIP or 28-pin HLCC, PLCC package tional I/O pins communicate to one logic array block. In the CY7C344 LAB there are 32 macrocells and 64 expander product terms. When an I/O macrocell is used as an input, two expanders are.
