SN74HCS27PWR

Inverter Gates Overview

The SN74HCS27PWR is a Texas Instruments logic gate integrated circuit belonging to the 74HCS series. It contains three independent NOR gates, each with three inputs, housed in a 14-TSSOP surface-mount package. The device operates on a supply voltage range of 2V to 6V and features Schmitt-trigger inputs for noise immunity. It supports output currents of 7.8mA at both high and low states. The component is rated for an operating temperature range of -40°C to +125°C and exhibits a maximum propagation delay of 12ns at 6V with a 50pF load.

Inverter Gates Feature Summary

• Integrates three independent 3-input NOR logic functions within a single compact package.
• Incorporates Schmitt-trigger input stages to enhance signal integrity and noise rejection capabilities.
• Designed for automotive applications with AEC-Q100 qualification ensuring reliability under harsh conditions.

Inverter Gates Applications

• Automotive electronic control units requiring robust logic processing
• Industrial systems utilizing noisy digital environments
• General-purpose logic circuits in consumer electronics

Inverter Gates Procurement Notes

Verify the specific suffix PWR corresponds to the TSSOP-14 package variant when sourcing. Confirm that the Q1 designation is absent from this specific part number, indicating it may not hold the formal AEC-Q100 automotive grade certification compared to the SN74HCS27QPWRQ1. Ensure compatibility with standard 74HCS logic families regarding voltage levels and drive strength requirements for the target application design.

Inverter Gates Selection Notes

Select this component when three separate 3-input NOR operations are required in a space-constrained design. The HCS series offers CMOS performance with TTL-compatible speeds. Consider the TSSOP-14 footprint constraints during PCB layout. Verify that the 2V to 6V supply range aligns with the system power architecture. Evaluate the need for Schmitt triggers versus standard inputs based on signal quality.

Inverter Gates Part Context

This part belongs to the Texas Instruments 74HCS family, which combines high-speed CMOS technology with low power consumption. The SN74HCS27 provides basic NOR logic functionality. It serves as a fundamental building block for complex digital logic designs. The device is manufactured using advanced semiconductor processes to ensure consistent performance across the specified temperature range.

Inverter Gates Replacement Considerations

The SN74HCS27QDRQ1 offers identical logical function but utilizes an SOIC-14 package instead of TSSOP. Both parts share the same electrical characteristics and series specifications. Designers must adjust footprints accordingly if substituting between these package types. No functional changes occur due to package variation alone.
