Microchip Technology's 27HC641-70-SP is a high-speed, 64K bit (8K x 8) One-Time Programmable (OTP) Read-Only Memory (ROM). This CMOS device offers a 70ns access time, suitable for applications requiring fast data retrieval. The memory organization is 8K words by 8 bits, with asynchronous operation and 3-state outputs for flexible system integration. Encased in a 24-pin Plastic Dual In-line Package (PDIP), it features through-hole mounting with a standard 2.54mm terminal pitch. Operating within a 4.5V to 5.5V supply voltage range, it is designed for use in industrial and commercial electronics, including legacy system upgrades and embedded control applications. The device exhibits a typical standby current of 40µA and a maximum operating current of 82mA.
