Inverter Gates datasheet and documents for SNJ54HC21J

SNJ54HC21J

Inverter Gates Overview

The SNJ54HC21J is a military-grade dual 4-input AND gate manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports an extended temperature range from -55°C to +125°C. The device features buffered inputs, balanced CMOS push-pull outputs, and standard high-impedance CMOS input structures. It provides significant power reduction compared to LSTTL logic ICs while supporting fanout up to 10 LSTTL loads.

Inverter Gates Feature Summary

Contains two independent 4-input AND gates performing the Boolean function Y = A • B • C • D
Balanced CMOS push-pull outputs capable of sinking and sourcing similar currents
Standard CMOS inputs with high impedance characteristics

Inverter Gates Applications

Combining power good signals
Enabling digital signals
Directly controlling motor controller reset pins requiring multiple active-high conditions

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'J' corresponds to the CDIP package variant. Confirm that the component status aligns with project requirements, as some variants may be marked NRND. Ensure compatibility with existing board layouts for the 14-pin ceramic DIP form factor.

Inverter Gates Selection Notes

Select this component when military-grade reliability and wide temperature operation are required. It is suitable for designs needing dual 4-input logic functions in a hermetic package. Consider thermal management if driving heavy capacitive loads, as output current limits must not be exceeded.

Inverter Gates Part Context

This part belongs to the SN54HC series, which represents high-speed CMOS logic designed for aerospace and defense applications. Unlike commercial SN74HC parts, the SN54HC series offers wider operating voltage and temperature ranges. The 'J' suffix specifically denotes the 14-pin Ceramic Dual In-Line Package (CDIP).
