74HC125T14-13

Buffers, Drivers, Receivers, Transceivers Overview

The 74HC125T14-13 is a quadruple 3-state buffer manufactured by Diodes Incorporated in the HC logic series. It provides four independent non-inverting buffers with separate active-low enable inputs (OE). The device operates within a supply voltage range of 2.0V to 6.0V and features Schmitt trigger action at all inputs for noise immunity. It sinks or sources 4mA at VCC = 4.5V and includes ESD protection exceeding JESD 22 standards. Packaged in TSSOP-14, it supports operation from -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type matches design requirements, as the 74HC125 family is available in both SO-14 and TSSOP-14 configurations. Confirm that the ordering suffix corresponds to the desired packaging format. Ensure compliance with RoHS and halogen-free specifications if required by project constraints. Cross-reference pin assignments and electrical characteristics against the official datasheet before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring buffered signals with high-impedance control capabilities. The inclusion of Schmitt triggers makes it suitable for noisy environments or slow-rising input signals. Verify that the operating voltage range aligns with the system's power supply rails. Consider the thermal performance and current drive capabilities relative to the load requirements of the connected downstream components.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74HC125 family of quadruple 3-state buffers produced by Diodes Incorporated. It utilizes standard HC logic technology, ensuring compatibility with other devices in the 74HC series. The T14 suffix indicates the TSSOP-14 surface-mount package variant. This family is widely used in digital electronics for signal buffering and bus driving applications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible alternatives include the 74HC125S14-13, which shares identical functionality but utilizes an SO-14 package instead of TSSOP-14. When substituting, verify that the physical footprint and pin spacing match the existing PCB layout. Electrical parameters such as propagation delay and output current should be compared to ensure equivalent performance in the target application.
