Synchronous FIFO in a 32-pin PLCC footprint
The SN74ACT72241L35RJ is a 4K x 9 synchronous FIFO from Texas Instruments, in a PQCC32 (plastic leaded chip carrier) package. This is the 35 ns access-time variant of the ACT72241 series, designed for buffering data between clock domains in 9-bit-wide datapaths. A 4K x 9 organization means it stores 4096 words of 9 bits each — the extra bit is typically used for parity. The synchronous interface latches data on a single clock edge, simplifying timing closure in bus-oriented systems compared to asynchronous FIFOs. The PQCC32 footprint is a JEDEC-standard PLCC-32, with 1.27 mm pitch leads on four sides. It occupies roughly 14 x 14 mm of board area and is socket-compatible with standard PLCC-32 sockets, making it field-replaceable without rework.
