Microchip Technology's 27HC641 series offers an 8K x 8 One-Time Programmable (OTP) Read-Only Memory (ROM) with a maximum access time of 55ns. This CMOS component, identified by part number 27HC641-55-P, features an 8-bit memory organization and operates asynchronously. The device utilizes a 24-pin PDIP (Plastic Dual In-line Package) with through-hole mounting, a terminal pitch of 2.54mm, and a body width of 0.6 inches. It supports a supply voltage range of 4.5V to 5.5V, with a nominal 5V operation. Typical applications for this memory device include industrial control systems, legacy system designs, and cost-sensitive embedded applications where firmware is finalized early in the design cycle. The output characteristics are 3-state, and it draws a maximum supply current of 94mA.
