Base product number: 74ALVC3641. RoHS non-compliant. Mounting: surface mount. Supplied in trays. Current stock availability: 350 units (subject to change).

Key Features

36K memory organized as 1K x 36

Synchronous FIFO operation for predictable timing

100 MHz data rate for high-throughput buffering

7.5 ns access time for fast response

Bi-directional bus interface

Programmable flags (status indicators for almost-full/empty, etc.)

Retransmit capability for data replay

Depth and width expansion to build larger FIFOs

Operates at 3.0 V to 3.6 V (low-voltage CMOS, ALVC)

Commercial temperature range 0°C to 70°C

132-pin BQFP bumpered package for robust handling

Surface-mount design, tray packaging

Key Advantages

Wide 36-bit data path reduces external glue logic for wide-bus systems

Synchronous design simplifies clocking and timing closure in high-speed designs

Flexible expansion (depth and width) scales to larger buffers without complex redesign

Programmable flags and retransmit simplify flow control and error recovery

Low-voltage operation helps reduce power consumption vs. older 5 V parts

Bumpered BQFP improves mechanical robustness during handling and assembly

Packaging

Type: 132-pin BQFP (bumpered), surface mount

Body size: 24.13 mm x 24.13 mm (square)

Pin configuration: Quad flat leads around all four sides, total 132 pins

Material: Molded plastic encapsulation with plated leads (standard industry construction)

Shipping: Tray

Thermal characteristics: Use standard SMT thermal practices; ensure adequate airflow and keep junction temperature within spec. Refer to datasheet for thermal resistance and power dissipation guidelines.

Electrical properties (package-level considerations): Supports high-speed synchronous operation up to 100 MHz; ensure signal integrity with controlled impedance routing, proper decoupling, and solid ground planes.

Lifecycle

Status: Mature product; availability can be limited and may vary by region. RoHS non-compliant variants are typically older and may not be recommended for new designs.

Potential equivalents or alternatives:

- Texas Instruments SN74V3641 family (similar synchronous FIFO concept; verify capacity, speed, and pinout)

- Renesas/IDT 72V361 family (1K x 36 synchronous FIFO; check pin compatibility and timing)

- Infineon/Cypress CY7C436x synchronous FIFO families (similar function; verify organization and interface details)

Note: Pin-compatibility and exact timing parameters differ between manufacturers. Always verify against datasheets before substituting.

If you need confirmed pin-compatible or drop-in alternatives, please contact our sales team via the Y-IC website for expert guidance and up-to-date cross-references.
