SN74HC125PWT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC125PWT is a quad bus buffer and line driver from the Texas Instruments SN74HC125 series, manufactured using advanced CMOS technology. It features four non-inverting buffers with three-state outputs housed in a 14-TSSOP surface-mount package. The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a high-level output current of -7.8 mA and a low-level output current of 7.8 mA. Propagation delay varies by voltage: 150 ns at 2 V, 30 ns at 4.5 V, and 25 ns at 6 V. It functions reliably across an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the TSSOP-14 package configuration. Ensure compatibility with the required operating temperature range and supply voltage specifications. Confirm RoHS compliance status and check for any recent product change notices or lifecycle status updates prior to finalizing procurement decisions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require multiple buffered signals with controlled output states. It is suitable for applications needing moderate drive capability and low static power dissipation. Consider the propagation delay characteristics relative to the system clock speed and verify that the 14-TSSOP footprint aligns with the PCB layout constraints.
