74ABT126CSJ

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT126CSJ is a quad buffer and line driver featuring three-state outputs, housed in a 14-lead Small Outline Package (SOP) with a 5.3mm width. It operates within a supply voltage range of +4.5V to +5.5V and supports an ambient temperature range of -40°C to +85°C. The device provides high output drive capabilities, including a sink current of 64mA and a source current of 32mA. Propagation delays are specified at a maximum of 4.6ns under standard conditions.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Non-inverting buffers with three-state outputs controlled by dedicated enable inputs
• High impedance glitch-free bus loading during the entire power-up and power-down cycle
• Nondestructive hot insertion capability allowing live bus connection and disconnection
• Disable time is less than enable time to prevent bus contention

Buffers, Drivers, Receivers, Transceivers Applications

• Partial power-down applications utilizing I_OFF circuitry
• Quad bus interface systems requiring high-speed buffering
• Live insertion and extraction permitted bus architectures

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package designation matches the required footprint, as the CSJ suffix indicates a 14-lead SOP variant. Confirm that the component meets the necessary RoHS compliance standards for your assembly process. Ensure that the operating environment remains within the specified -40°C to +85°C temperature range to maintain guaranteed latchup protection and electrical performance specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad non-inverting buffer with three-state control is required for TTL-level interfacing. The ABT logic family offers BiCMOS high speed and robust output drive suitable for driving multiple loads. Consider the specific SOP package dimensions if space constraints exist, and verify that the 4.5V to 5.5V supply voltage aligns with the system power architecture.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the 74ABT logic series, which utilizes BiCMOS technology to deliver high-speed performance comparable to advanced bipolar devices while maintaining CMOS low power consumption. The 74ABT126 specifically functions as a quad buffer with three-state outputs, designed for high-performance digital signal routing and bus isolation in complex electronic systems.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74ABT126D and 74ABT126PW are documented equivalents within the same family, offering identical logical functionality but differing in package type (SOIC and TSSOP respectively). Verify pin compatibility and thermal characteristics when substituting these variants.
