74HCT3G07DP,125

Overview

The Nexperia 74HCT3G07DP,125 is a triple buffer with open-drain outputs housed in an SOT505-2 (TSSOP8) package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features TTL input levels and includes clamp diodes on inputs for overvoltage tolerance. Static characteristics specify a maximum low-level output voltage of 0.4 V at 4.0 mA load current. Dynamic performance at 4.5 V indicates a typical OFF-state to LOW propagation delay of 11 ns and a HIGH to LOW transition time of 6 ns.

Feature Summary

• Triple non-inverting buffer configuration with open-drain outputs
• TTL-compatible logic input levels for direct interfacing
• Input clamp diodes enable operation with voltages exceeding the supply rail

Applications

• Open-drain bus line driving applications
• Voltage level translation between different logic domains
• Driving loads requiring external pull-up resistors

Selection Notes

Select this component when a triple buffer with open-drain capability is required for TTL-level signal processing. The TSSOP8 package offers a compact footprint suitable for space-constrained designs. Ensure the application circuit includes appropriate external pull-up resistors connected to the desired voltage rail, as the outputs cannot source current internally.

Part Context

This part belongs to the Nexperia 74HCT series of high-speed CMOS logic devices. The HCT series is specifically designed to be pin-compatible and functionally equivalent to standard TTL logic families while utilizing CMOS technology for lower power consumption. The '3G' designation indicates a triple gate function packaged in a small outline form factor.

Replacement Considerations

The 74HC3G07DP serves as a functional alternative if CMOS input levels are acceptable instead of TTL levels. Other single or dual buffer variants within the 74HCT family may be considered if fewer channels are sufficient, provided the package and electrical specifications align with the design requirements.
