SNJ54AHC125J

Overview

The SNJ54AHC125J is a quadruple bus buffer gate featuring four independent line drivers with three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 5.5V and supports an operating temperature range from -55°C to 125°C. The device utilizes a 14-pin Ceramic Dual In-Line Package (CDIP). Each output is individually controlled via dedicated enable pins; the output assumes a high-impedance state when the associated enable input is high, allowing for effective bus isolation.

Feature Summary

Features four individual output enable pins for independent control of each buffer gate
Provides high-impedance state during power-up or power-down when OE is tied to VCC through a pullup resistor
Latch-up performance exceeds 250mA per JESD 17 specification

Applications

Flow Meters
Programmable Logic Controllers
Power Over Ethernet (PoE)
Motor Drives and Controls
Electronic Point-of-Sale

Procurement Notes

Verify that the component matches the SNJ54AHC125J designation specifically, as this indicates the military-grade SN54 variant in CDIP packaging. Confirm the manufacturer is Texas Instruments. Ensure the package type is 14-pin CDIP. Check for MIL-PRF-38535 compliance if required for your application. Validate the date code and lot traceability against your quality standards.

Selection Notes

Select this component when a wide operating voltage range from 2V to 5.5V is required alongside extended temperature capabilities down to -55°C. The SNJ54AHC125J is suitable for applications needing individual control over four separate data lines. Consider the CDIP package for through-hole mounting requirements. Ensure the design accounts for the necessary pullup resistors on the OE pins to maintain high-impedance states during power transitions.

Part Context

This part belongs to the SNx4AHC125 family of quadruple bus buffer gates with three-state outputs. The 'SNJ' prefix denotes the SN54 series, which typically meets military specifications and offers a wider operating temperature range compared to the commercial SN74 variants. The 'AHC' suffix indicates Advanced High-Speed CMOS technology, providing faster switching speeds while maintaining low power consumption.
