This document describes the features and characteristics of the Philips Semiconductors 74F225 16X5 asynchronous FIFO product, including independent synchronous inputs and outputs, organized as 16 words of 5 bits, DC to 25MHz data rate, and 3-state outputs.
The Philips 74F225 is an 80-bit active element First-In-First-Out (FIFO) integrated circuit organized as 16 words of 5 bits. It features independent synchronous inputs and outputs, with 3-State outputs controlled by a single enable input (OE). The device processes data in a parallel format at clock rates from DC to 25MHz and is designed for easy expansion in multiples of 16-words of 5-bits.
The datasheet provides detailed information on the device's features, pin configuration, logic diagrams, and electrical characteristics. It includes absolute maximum ratings, recommended operating conditions, DC and AC electrical characteristics, and typical timing diagrams to assist in design and application.
