SNJ54HC08J

Inverter Gates Overview

The SNJ54HC08J is a quadruple 2-input positive-AND gate from the HC/UH series, manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 6V and supports an operating temperature range of -55°C to +125°C. The device features buffered inputs and balanced CMOS push-pull outputs capable of driving up to 10 LSTTL loads. It utilizes a 14-pin ceramic dual in-line package (CDIP) with hermetic sealing.

Inverter Gates Feature Summary

• Contains four independent 2-input AND gates performing Boolean logic Y = A ● B
• Balanced CMOS push-pull outputs for similar sourcing and sinking currents
• Standard high-impedance CMOS inputs requiring fast edge rates
• Integrated positive and negative clamping diodes on all inputs and outputs

Inverter Gates Applications

• Combining power good signals
• Enabling digital signals
• Generating multi-input AND functions by combining internal gates

Inverter Gates Procurement Notes

Verify the specific ordering suffix against the Package Option Addendum to confirm the CDIP (J) package configuration. Ensure the component meets the required military or aerospace specifications if indicated by the part marking, as standard commercial variants may differ in environmental qualification.

Inverter Gates Selection Notes

Select this component when a wide operating temperature range (-55°C to +125°C) and robust ceramic packaging are required. It serves as a direct replacement for other SN54HC08 variants in the HC series, provided the pinout and logic function match the design requirements.

Inverter Gates Part Context

This device belongs to the SNx4HC08 family of quadruple 2-input AND gates. It shares functional characteristics with SN74HC08 but is distinguished by its extended temperature range and specialized packaging options suitable for harsh environments.

Inverter Gates FAQ

How should unused inputs be handled?

All unused inputs must be terminated to either VCC or ground to prevent undefined operational states and excessive current consumption.

What is the maximum recommended capacitive load?

The datasheet recommends ensuring the capacitive load at the output is less than or equal to 70 pF for optimal performance.
