Packaging

Shipment format: Tray

Package type: HLQFP/LQFP

Material: Molded epoxy plastic per JEDEC standards, tin-lead or lead-free plating depending on lot (RoHS non-compliant as noted)

Size: 14 mm x 14 mm body, nominal height per LQFP spec

Pin count and configuration: 120 pins total; includes 36-bit data interface, control and clock pins for read/write, status flags, power and ground distribution; verify exact pinout in datasheet

Mounting: Surface-mount (SMT), gull-wing leads

Thermal characteristics: Standard LQFP thermal behavior; ensure good PCB copper area and airflow; derate power in high ambient; operate within 0°C to 70°C

Electrical properties summary: 3.0–3.6 V supply, 50 MHz data rate, 11.5 ns access time, bi-directional bus, synchronous control; current supply max listed as 350A in provided data (likely a typographical error—confirm the correct current in the datasheet)

Lifecycle

Status insight: The 74ALVC FIFO family is mature; some variants have limited availability in certain regions. This specific suffix -20PCB may be specialized or older and could be near discontinuation depending on date and source. Y-IC can help confirm the latest status and locate inventory.
