SN74F352N

Overview

The SN74F352N is a dual 4-line to 1-line data selector/multiplexer from the Texas Instruments SN74F series. It integrates two independent multiplexers with built-in decoders and latches, housed in a 16-pin PDIP package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports through-hole mounting. It features low-level output current of 32 mA and high-level output current of -8 mA, with a propagation delay of 10 ns at 5 V. The component functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrates two independent 4-input multiplexers with built-in decoders and latches for efficient signal routing
• Provides open-collector outputs suitable for wired-OR configurations and bus-oriented systems
• Supports direct interface with TTL logic families due to compatible input/output characteristics

Applications

• Data routing in digital communication systems
• Address decoding in memory systems
• Signal selection in microprocessor-based designs

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout and electrical specifications. Ensure the procurement channel provides authentic Texas Instruments components with traceable documentation. Confirm that the PDIP-16 package matches the target PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when dual independent 4-to-1 multiplexing with decoding capability is required in through-hole designs. Consider the open-collector output structure for applications needing wired-OR logic or level shifting. Verify that the 5V supply voltage and commercial temperature range align with the system environment constraints.

Part Context

The SN74F352N belongs to the SN74F (Fast) logic family, known for improved speed over standard TTL while maintaining compatibility. This series was widely used in 1980s and 1990s digital systems. The 'N' suffix denotes the plastic DIP package variant manufactured by Texas Instruments for general-purpose digital logic applications.

Replacement Considerations

Compatible substitutes include the SN74LS153N for similar functionality with lower power consumption, though switching speeds differ. The SN74F153N offers equivalent performance within the same F-series family. Verify pin compatibility and electrical parameters before substitution.
