SNJ54H11W is listed in the Inverter Gates range at ChipApex. The manufacturer field lists Texas Instruments. Its product description is IC GATE AND 3-INP. Review the specifications below when checking this part for your BOM.
The SNJ54H11W is a military-grade triple 3-input AND gate manufactured by Texas Instruments. It belongs to the H-TTL logic series and utilizes a ceramic flatpack (FP) package with 14 pins. The device operates within a supply voltage range of 4.5 V to 5.5 V. It supports an operating temperature range from -55 °C to 125 °C, ensuring reliability in harsh environments.
Verify the manufacturer source carefully, as Rochester Electronics also lists this part number. Confirm that the specific unit matches the Texas Instruments H-TTL specification sheet rather than generic equivalents. Ensure the ceramic flatpack package type aligns with the design requirements before procurement.
Select this component when military-grade radiation tolerance and wide temperature operation are required. The H-TTL series offers faster switching speeds compared to standard TTL variants. Verify pin compatibility with existing footprints if replacing older designs.
This part is part of the SNJ54xx series, which denotes military-grade performance. It serves as a fundamental logic building block for complex digital circuits requiring high noise immunity and stable operation under extreme thermal conditions typical in defense and space sectors.
SN54H11W is the commercial grade equivalent. SNJ54LS11W is a low-power Schottky alternative with different speed and power characteristics.
