SN74F151BNE4

Overview

The SN74F151BNE4 is an 8-line to 1-line multiplexer from the Texas Instruments F logic family, housed in a 16-pin PDIP package. It provides full binary decoding to select one of eight data sources based on three address inputs (A, B, C). The device features active-low strobe functionality and complementary outputs (Y and W). Recommended operating conditions specify a supply voltage range of 4.5 V to 5.5 V. Electrical characteristics indicate a typical propagation delay of 9.5 ns for the A/B/C-to-W path at 5 V. Operating temperature range is defined from 0°C to 70°C.

Feature Summary

• Provides full binary decoding to select one of eight independent data sources
• Features active-low strobe input to enable or disable the multiplexing function
• Delivers both non-inverted (Y) and inverted (W) output signals simultaneously

Applications

• Boolean function generation circuits
• Parallel-to-serial data conversion systems
• Data source selection mechanisms

Procurement Notes

Verify that the specific ordering suffix 'E4' corresponds to the required lead finish and RoHS compliance status as listed in the Package Option Addendum. Confirm the package type matches the design requirements, as this part number specifically denotes the PDIP variant. Ensure the application environment remains within the specified commercial temperature limits of 0°C to 70°C.

Selection Notes

Select this component when high-speed switching is required within standard TTL voltage levels. The F series offers faster propagation delays compared to HC or HCT families but consumes more power. Verify that the PCB layout supports through-hole mounting for the 16-pin DIP configuration. Consider the complementary outputs if both true and complemented signals are needed for downstream logic stages.

Part Context

This device belongs to the SN74F151B family of monolithic data selectors. It serves as a standard solution for routing multiple digital signals onto a single line under control of binary address inputs. The 'N' suffix indicates the plastic dual in-line package option, while 'E4' typically signifies environmental compliance attributes defined by the manufacturer's packaging standards.

FAQ

How does the strobe input affect the outputs?

When the strobe input is at a high logic level, the Y output is forced low and the W output is forced high, regardless of the state of the data or address inputs.

What is the maximum supply voltage allowed?

The recommended operating conditions specify a maximum supply voltage (VCC) of 5.5 V.
