DESCRIPTION

· The 74HC7403-Q100 and 74HCT7403-Q100 are expandable FIFO memories organized as 64 words by 4 bits, ideal for high-speed applications with a guaranteed 15 MHz data-rate.

· Features include separate shift-in and shift-out controls for independent read/write operations, master-reset input, output enable input, and status flags.

· Qualified to AEC-Q100 (Grade 1) for automotive applications, with inputs including clamp diodes for interfacing with voltages exceeding VCC.

FEATURES

· Automotive qualification per AEC-Q100 (Grade 1), operational from -40°C to +125°C.

· Supports synchronous or asynchronous operation with typical shift rates of 30 MHz.

· Expandable in word and bit dimensions, with pinning designed for easy board layout.

· Input levels: CMOS for 74HC7403-Q100, TTL for 74HCT7403-Q100; 3-state outputs.

· Complies with JEDEC standard JESD7A, with robust ESD protection exceeding industry standards.

APPLICATIONS

· Suitable for high-speed disc or tape controllers and communications buffers.
