Functional operation of this device at other conditions beyond those listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliability.

The 37845 chip family is a low-power, 4096K (4,194,304) bits, +3.3V electrically one-time programmable (OTP) read-only memories (EPROM). Organized into 256K words with 16 bits per word, 37845 features a fast single address location programming, typically at 75s per word. Any word can be accessed in less than 90ns with respect to spec. This eliminates the need for WAIT states in high-performance microprocessor systems. The 37845 has separate Output Enable (OE) and Chip Enable (CE) controls which eliminate bus contention issues.
