74HCT125FP-E

Overview

The HD74HCT125FP-E is a quad bus driver manufactured by Renesas Electronics Corporation, belonging to the HCT logic series. It features four independent one-bit buffers with true outputs and three-state capabilities housed in a 14-pin plastic dual small-outline package (PDSO14). The device operates within a temperature range of -40 °C to 85 °C and supports LSTTL output logic level compatibility alongside CMOS output compatibility.

Feature Summary

• Provides high-speed operation suitable for demanding digital applications
• Features three-state outputs controlled by dedicated input signals
• Ensures compatibility with LSTTL and CMOS logic levels

Applications

• High-speed data buffering systems
• Digital signal routing interfaces
• LSTTL-to-CMOS translation circuits

Procurement Notes

Verify the specific manufacturer designation, as official documentation references the Hitachi or Renesas prefix HD74HCT125FP-EL. Confirm that the suffix corresponds to the exact packaging and environmental specifications required for your design implementation.

Selection Notes

Select this component when requiring a quad buffer with active-low control inputs to enable high-impedance states. Ensure the system voltage aligns with standard HCT series requirements and verify thermal constraints against the specified operating temperature limits.

Part Context

This part belongs to the broader 74HCT125 family of quad bus buffers. While other variants may exist in different packages or with varying control polarities, this specific model provides non-inverting functionality with low-level control activation for the high-impedance state.

Replacement Considerations

Consult official datasheets for cross-reference candidates from other manufacturers offering identical pinouts and electrical characteristics. Verify functional equivalence regarding control polarity and output drive strength before substitution.
