SN74S478J

OTP ROM, 8KX8, 100ns, TTL, CDIP24

Manufacturer: Texas Instruments

Categories: OTP ROMs

Quality Control: Learn More

The Texas Instruments SN74S478J is an 8K x 8 One-Time Programmable (OTP) Read-Only Memory (ROM) component. This asynchronous memory device features a maximum access time of 100ns and operates with TTL (Transistor-Transistor Logic) technology. The memory organization is 8K words by 8 bits, providing a total density of 65,536 bits. It is housed in a 24-lead Ceramic Dual In-line Package (CDIP), suitable for through-hole mounting. The operating supply voltage range is 4.5V to 5.5V, with a nominal 5V requirement. Typical applications for this type of memory can be found in industrial control systems and legacy data storage solutions. The component has a maximum supply current of 140mA and operates within a temperature range of 0°C to 70°C.

Integrated Circuit FAQs

An integrated circuit (IC) is a semiconductor chip that contains transistors, resistors, capacitors, and other electronic components on a single silicon substrate. ICs are the foundation of modern electronics and power devices such as smartphones, computers, automotive systems, and industrial equipment.

Integrated circuits work by routing electrical signals through microscopic semiconductor components fabricated onto a silicon chip. Depending on the design, ICs can process, amplify, store, or control electronic data.
