SNJ54ACT00J

Inverter Gates Overview

The SNJ54ACT00J is a military-grade quadruple 2-input positive-NAND gate manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and features TTL-voltage compatible inputs that accept voltages up to 5.5V. The device provides high-speed performance with a maximum propagation delay of 8ns at 5V. It utilizes a hermetically sealed 14-pin Ceramic Dual In-Line Package (CDIP) designed for robust operation across an extended temperature range from -55°C to 125°C.

Inverter Gates Feature Summary

• Contains four independent 2-input NAND gates performing Boolean logic functions
• TTL-voltage compatible inputs allow direct interfacing with TTL logic systems
• High-speed switching capability with low propagation delay characteristics

• Communication equipment utilizing high-speed data transmission protocols

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'J' corresponds to the CDIP-14 package configuration. Confirm RoHS exemption status as military parts often differ from commercial standards. Ensure the supplier provides traceability documentation required for defense applications. Check current production status, as this part may be designated as Not Recommended for New Designs.

Inverter Gates Selection Notes

Select this component when system requirements mandate military-grade environmental resilience and extended temperature tolerance. The ACT series offers superior speed compared to standard LS or HC families while maintaining CMOS power efficiency. Verify input compatibility with existing TTL drivers to ensure proper logic level translation without additional buffering components.

Inverter Gates Part Context

This device belongs to the SN54ACT family, which represents advanced CMOS technology optimized for high-speed digital applications. Unlike commercial SN74 variants, the SN54 prefix indicates qualification for military specifications, including stricter testing for reliability and longevity. The ACT series bridges the performance gap between older bipolar technologies and modern CMOS solutions.

Inverter Gates FAQ

What is the logic function performed by each gate?

Each gate performs the Boolean function of Y = A•B or Y = A+B in positive logic.

Can unused inputs be left floating?

No, all unused inputs must be held at VCC or GND to ensure proper device operation and prevent undefined states.
