Texas Instruments TMS62457-45DJ is a 1 Mbit CMOS standard SRAM with a memory organization of 256K x 4 bits. This asynchronous SRAM offers a maximum access time of 45ns, making it suitable for applications requiring rapid data retrieval. The component operates with a nominal supply voltage of 5V and features separate I/O. Its 3-state output characteristics and dual-terminal configuration are key design aspects. Packaged in a 32-lead plastic small outline J-lead (SOJ) package with a 1.27mm terminal pitch, it is designed for surface mounting. Typical applications for this memory component include consumer electronics and industrial control systems where reliable and fast static RAM is essential. The standby current is rated at 2mA maximum, with a standby voltage minimum of 4.5V.
