Detailed Description

High-speed synchronous dual FIFO memory in the 74ABT family. Total memory 18K (512 × 18 × 2). Operates from a 5 V supply (4.5–5.5 V), supports up to 100 MHz data rates, and delivers 8 ns access time. Bi-directional data path, programmable flag outputs, and simple synchronous control signals. Commercial temperature range 0–70°C. 80-lead QFP/BQFP package, tray-packed. RoHS non-compliant (leaded finish).

Key Features

Dual synchronous FIFO: 512 × 18 per channel (total 18K)

100 MHz max data rate for high-throughput buffering

8 ns access time for tight timing budgets

4.5–5.5 V supply; ABT logic family for robust 5 V operation

Bi-directional bus for flexible data flow

Programmable flags (almost-full/almost-empty) supported

Retransmit capability: No

First-Word-Fall-Through (FWFT): No

Max supply current: 95 mA

Operating temperature: 0°C to 70°C (commercial)

RoHS status: Non-compliant (leaded)

Base product number: 74ABT7819

Series: 74ABT

Mounting type: Surface mount (SMT)

Package: 80-QFP/BQFP (14 × 20 mm), supplier device package 80-QFP (14 × 20)

Available quantity at Y-IC: 2792 units

Key Advantages

Fast timing (8 ns) and 100 MHz throughput reduce system latency

Stable 5 V ABT logic with strong noise margins for legacy and industrial designs

Dual-channel FIFO consolidates buffering; fewer ICs and simpler routing

Programmable flags make flow control straightforward and reliable

Mature, well-understood TI architecture; easier integration and support

Wide supply range tolerance (4.5–5.5 V) adds design robustness

SMT QFP package saves board space compared to socketed memory solutions

Packaging

Type: 80-lead BQFP/QFP surface-mount IC

Shipment form: Tray

Body size: 14 mm × 20 mm; low-profile quad flat package

Materials: Molded epoxy body; copper-alloy leadframe; tin–lead plated gull-wing leads (RoHS non-compliant)

Pin configuration: 80 perimeter pins with dedicated data buses (18-bit per channel), clock inputs, read/write enables, output enable, reset, and programmable flag outputs (full/empty/almost-full/almost-empty); bi-directional data I/O

Thermal characteristics: Designed for operation from 0°C to 70°C; heat removal primarily via leads and PCB copper; follow TI layout and copper area guidelines for best thermal performance; actual thermal resistance depends on board stack-up and airflow

Electrical properties: 4.5–5.5 V VCC; 95 mA max supply current; 100 MHz max data throughput; 8 ns access time; ABT logic levels compatible with 5 V TTL/CMOS inputs

Lifecycle

Status: The 74ABT FIFO family is mature. Availability can vary by region and date. This device may be limited or not recommended for new designs in some programs. Check current status with Y-IC for the most up-to-date supply outlook.

Equivalent or alternative models (evaluate fit, pinout, voltage, and timing carefully):

- Renesas/IDT 72V364, 72V366 series: 512 × 18 synchronous FIFO families (3.3 V variants exist); different pinouts and logic levels

- Renesas/IDT 72V361/72V362 families: Related synchronous FIFOs; capacities and widths vary; verify control timing

- Infineon (Cypress) CY7C433/436 series: 18-bit synchronous FIFO families; capacities vary; check whether single vs dual and voltage requirements

- Texas Instruments SN74V36x families: TI synchronous FIFO series (often 3.3 V); confirm capacity, FWFT behavior, and package

- NXP and ON Semiconductor ABT/FAST families: Some logic FIFOs exist; confirm dual-channel availability and flag behavior
