SN74ALS233BN

FIFOs Memory Overview

The SN74ALS233BN is an asynchronous first-in, first-out (FIFO) memory device manufactured by Texas Instruments. It features a data bus width of 4 bits and a storage capacity of 64 bits, organized as 16 words by 4 bits. The component operates within a supply voltage range of 4.5 V to 5.5 V, with a maximum power supply current of 125 mA. It supports unidirectional bus orientation and contains two circuits. The device is designed for operation at temperatures between 0°C and +70°C and is housed in a PDIP-16 package.

FIFOs Memory Feature Summary

• Asynchronous FIFO memory architecture for temporary data buffering
• Unidirectional data transfer capability
• Standard TTL-compatible logic family integration

FIFOs Memory Applications

• Data buffering in microprocessor systems
• Interface bridging between devices with different clock domains
• Temporary storage in serial-to-parallel conversion circuits

FIFOs Memory Procurement Notes

Verify the specific suffix 'BN' against the manufacturer's official datasheet to confirm the PDIP-16 through-hole package configuration. Ensure the asynchronous nature aligns with system timing requirements. Confirm RoHS compliance status directly from the latest production documentation before procurement.

FIFOs Memory Selection Notes

Select this component when a low-cost, asynchronous FIFO solution is required for 4-bit data paths. The SN74ALS series offers faster switching speeds compared to standard LS logic. Verify that the 16-word depth meets the buffer requirements and that the unidirectional flow matches the application design.

FIFOs Memory Part Context

This part belongs to the SN74ALS233B family of asynchronous FIFO memories. It is distinct from synchronous variants like the SN74ALS233, which may feature different timing characteristics. The ALS series provides improved speed-power product over previous generations while maintaining pin compatibility with standard logic families.

FIFOs Memory Replacement Considerations

Direct substitutes include other SN74ALS233 variants with compatible packages. Cross-reference with SN74ALS233BDW for surface mount options if lead-free assembly is required. Verify electrical specifications match exactly before substitution.
