SN74F151BN

Overview

The SN74F151BN is an 8-input, single-output data selector and multiplexer from the Texas Instruments SN74F series. It utilizes bipolar technology and features a 16-pin PDIP package designed for through-hole mounting. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a commercial temperature range of 0°C to +70°C. Key electrical specifications include a propagation delay of 9.5 ns and a maximum low-level output current (IOL) of 20 mA.

Feature Summary

• Provides high-speed data selection with a propagation delay of 9.5 ns
• Features a push-pull output stage capable of driving standard TTL loads
• Includes active-low enable input for controlling data flow

Applications

• Data routing in digital communication systems
• Address decoding logic circuits
• Parallel-to-serial data conversion modules

Procurement Notes

Verify that the specific part number suffix 'BN' corresponds to the PDIP-16 package variant. Confirm RoHS compliance status as it may vary by production batch or region. Ensure the ordering quantity aligns with the manufacturer's standard tube packaging requirements for this specific through-hole component type.

Selection Notes

Select this component when high switching speed is required compared to standard LS series alternatives. The F-series offers superior performance while maintaining pin compatibility with legacy designs. Verify that the 20 mA output drive capability meets the load requirements of the downstream circuitry without exceeding absolute maximum ratings.

Part Context

This component belongs to the SN74F family, which represents fast bipolar logic technology. It serves as a functional equivalent to the older SN74S151 but with optimized power-delay product characteristics. The device is widely used in applications requiring rapid data path switching within standard 5V logic environments.

Replacement Considerations

The SN74LS151N is a compatible alternative offering lower power consumption at the cost of reduced speed. For surface-mount implementations, consider the SN74F151D variant which maintains identical electrical performance in a SOIC package.
