74HC2G126DP,125

Overview

The Nexperia 74HC2G126DP,125 is a dual buffer and line driver featuring three-state outputs controlled by active-low output enable inputs (nOE). It operates within a supply voltage range of 2.0 V to 6.0 V and utilizes CMOS input levels. The device incorporates input clamp diodes for interfacing with voltages exceeding VCC. It is housed in an SOT505-2 TSSOP8 package and supports operating temperatures from -40 °C to +125 °C.

Feature Summary

• Dual non-inverting buffers with three-state outputs controlled by dedicated enable pins
• Wide operating voltage range supporting 2.0 V to 6.0 V supply rails
• Input clamp diodes allow current limiting resistors for interfacing above VCC
• High noise immunity and low power dissipation characteristics

Applications

• Signal buffering in mixed-voltage environments
• Line driving for high-speed data transmission
• Interface translation between different logic families
• Bus-oriented applications requiring tri-state control

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the component status aligns with current production availability. Ensure compliance with JEDEC standards and RoHS directives as specified in the product documentation before finalizing procurement orders.

Selection Notes

Select this component when dual buffered signals require independent three-state control. The wide voltage range accommodates systems operating between 2.0 V and 6.0 V. Verify that the TSSOP8 package dimensions fit the target PCB layout constraints and thermal requirements.

Part Context

This part belongs to the 74HC/HCT family of high-speed silicon-gate CMOS logic devices. It provides two independent buffers within a compact surface-mount package. The design ensures symmetrical output impedance and balanced propagation delays for reliable signal integrity.

Replacement Considerations

The 74HCT2G126DP,125 serves as a TTL-compatible alternative within the same package. Other variants include the DC (VSSOP8) and GD (XSON8) package options.
