SN74HCS240QWRKSRQ1

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HCS240QWRKSRQ1 is an automotive-grade octal inverting line driver featuring Schmitt-trigger inputs and three-state outputs. It operates within a supply voltage range of 2 V to 6 V, with a typical supply current of 2 µA and input leakage current of ±100 nA at 6 V. The device provides balanced output drive capabilities, sourcing or sinking up to 7.8 mA at 6 V. Propagation delay ranges from 6 ns to 16 ns depending on the supply voltage. It is qualified under AEC-Q100 standards for Grade 1, supporting ambient temperatures from -40°C to +125°C.

• Schmitt-trigger inputs provide high noise immunity and tolerance for slow signal transitions.
• Three-state outputs allow connection to bus lines with controlled high-impedance states.
• Automotive qualification ensures reliability across extended temperature ranges.

Buffers, Drivers, Receivers, Transceivers Applications

• Enabling or disabling digital signals in automotive systems
• Eliminating slow or noisy input signals through hysteresis
• Holding signals during controller reset sequences
• Switch debouncing applications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the Q1 series includes multiple form factors. Confirm the device meets the necessary AEC-Q100 grade requirements for your specific application environment. Ensure all unused inputs are terminated properly to prevent undefined logic states and excessive power consumption.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when driving long traces or transmission lines requiring signal integrity maintenance. The Schmitt-trigger architecture is essential for environments with significant electrical noise or slow-rising input edges. Consider the thermal characteristics of the WRKS package if operating near maximum junction temperatures.
