SN54LS125AJ

Buffers, Drivers, Receivers, Transceivers Overview

The SN54LS125AJ is a quadruple bus buffer with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of -55°C to 125°C. The device features low-level enabling control, non-inverting logic, and high-impedance disabled states. Electrical characteristics include a maximum propagation delay of 25 ns at 5 V, a low-level output current capability of 24 mA, and a high-level output current of -2.6 mA. It is housed in a 14-pin ceramic dual in-line (CDIP) package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides four independent bus buffers with separate enable controls for each channel.
• Outputs enter a high-impedance state when disabled, preventing significant loading on the bus.
• Features enhanced drive capability at high logic levels to support heavily loaded bus lines without external pullup resistors.

Buffers, Drivers, Receivers, Transceivers Applications

• Military and defense electronic systems requiring wide temperature tolerance
• High-reliability data bus buffering applications
• Industrial control systems operating in extreme environments

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the component matches the specific military-grade SN54LS125AJ designation rather than commercial variants. Confirm the CDIP package type and hermetic seal integrity are required for the application environment. Check for QML certification status if the design mandates compliance with MIL-PRF-38535 standards. Ensure the ordering suffix corresponds to the correct tube packaging format.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quadruple bus buffer with three-state outputs is required for military or industrial applications. The LS logic family offers lower power consumption compared to standard TTL. The wide operating temperature range makes it suitable for harsh environments where commercial grade parts would fail. Verify that the low-level enable logic aligns with the system control architecture.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN54LS125A series of quadruple bus buffers with three-state outputs. The 'SN54' prefix indicates a military-grade device capable of operating over an extended temperature range. The 'LS' suffix denotes Low-power Schottky logic technology. The 'J' suffix specifies the ceramic dual in-line package construction.
