The SN74ACT3641-15PCB is a synchronous FIFO (First In, First Out) memory chip manufactured by Texas Instruments. It features a storage capacity of 36K (1K x 36) bits and operates bi-directionally at a clock speed of 66.7 MHz with an access time of 11 nanoseconds. The device is housed in a 120-pin HLQFP package with dimensions of 14x14 mm. It functions within a voltage range of 4.5 V to 5.5 V and draws a current of 400µA. This FIFO memory chip is designed to efficiently manage data flow in applications where temporary data storage is required, interfacing smoothly with digital systems that demand precise timing and synchronization.
