M74HC153B1R

Overview

The M74HC153B1R is a dual 4-channel multiplexer manufactured by STMicroelectronics, housed in a 16-DIP package. It operates on a DC supply voltage of 5.00 V with an output current capability of 25 mA. The device features two independent circuits, each providing four non-inverting outputs. The output voltage range is specified between 0.5V and 0.5V, indicating specific logic level characteristics for this component variant.

Feature Summary

• Dual configuration providing two independent 4-to-1 multiplexing channels
• Non-inverting signal path for direct data routing
• High-speed CMOS fabrication using silicon gate C2MOS technology

Applications

• Data routing in digital communication systems
• Address decoding in microprocessor interfaces
• Signal selection in measurement instrumentation

Procurement Notes

Verify the obsolete status of the M74HC153B1R before procurement planning. STMicroelectronics indicates this product is no longer manufactured and will cease stocking once existing inventory is depleted. Ensure final design implementations account for end-of-life constraints and potential supply chain discontinuation risks associated with legacy DIP packages.

Selection Notes

Select this component only if legacy 16-DIP compatibility is required for existing board layouts. Consider the HC logic family specifications regarding input levels and propagation delays. Evaluate alternative active components if long-term availability is critical, as this specific part number faces manufacturing cessation.

Part Context

This part belongs to the M74HC153 series of dual 4-channel multiplexers. It shares functional similarities with other HC series devices but is distinct due to its specific DIP packaging and dual-channel architecture. The B1R suffix typically denotes specific tape-and-reel or bulk packaging variations within the manufacturer's catalog structure.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, engineers must identify equivalent active parts from current STMicroelectronics portfolios or third-party manufacturers that match the 16-DIP footprint and electrical specifications.
