It clocks at 133 MHz with a 5 ns access time, making it suitable for rate-matching or temporary storage in data acquisition, telecom line cards, and industrial control backplanes where the bus runs at moderate speed and the data word includes a parity or control bit alongside 16 data bits. ## 133 MHz clock and 5 ns access — what they mean for bus timing The 133 MHz maximum clock rate sets the synchronous interface speed for read and write operations. The 5 ns access time from clock edge to data valid gives the receiving logic a narrow but workable setup window at full speed. If the downstream device has a tighter hold requirement, the FWFT (First-Word Fall-Through) mode lets the first word appear on the outputs without a read cycle, cutting one clock of latency on the initial read. ## Feature set: programmable flags, depth/width expansion Programmable almost-full and almost-empty flags let the designer set watermark thresholds in software or via pin strapping, reducing host interrupt overhead. Expansion in depth or width is supported by cascading multiple devices — useful when the 4K x 18 native size is insufficient. Note that retransmit capability is not provided, so the FIFO cannot replay stored data without a full reset and re-fill. ## Supply and temperature range Operates from a 3 V to 3.6 V supply, typical for 3.3 V logic families. Maximum supply current is 35 mA. The 0°C to 70°C commercial temperature range limits use to indoor, temperature-controlled environments — not rated for industrial or automotive extended-temperature applications. ## Package and footprint Supplied in a 64-TQFP (10x10 mm) surface-mount package. The 0.5 mm pitch TQFP is a standard footprint for moderate-I/O logic devices, routable on two-layer boards with careful trace spacing. ## Lifecycle and sourcing The SN74V245-7PAG is listed as Active and ROHS3 compliant.","metaTitle":"SN74V245-7PAG synchronous FIFO, 133 MHz, 5 ns access","metaDescription":"TI SN74V245-7PAG synchronous FIFO memory: 72K (4K x 18), 133 MHz data rate, 5 ns access time, 64-TQFP.
