74HCT2G16GWH

Overview

The Nexperia 74HCT2G16GWH is a dual buffer gate manufactured using high-speed silicon-gate CMOS technology. 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 provides two non-inverting buffers in a TSSOP6 (SOT363-2) package with six leads. Key electrical characteristics include a maximum propagation delay of 29 ns at 4.5 V with a 50 pF load, input leakage current not exceeding ±1.0 μA, and ESD protection exceeding 2000 V under the Human Body Model standard.

Feature Summary

• Provides two independent non-inverting buffer channels for signal transmission
• Features high noise immunity and balanced propagation delays
• Includes electrostatic discharge protection compliant with JEDEC standards

Applications

• Signal buffering in mixed-voltage digital systems
• Level translation between TTL-compatible logic families
• General-purpose buffering for data lines in consumer electronics

Procurement Notes

Verify the specific ordering suffix 'H' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Ensure the selected variant matches the required operating temperature range and package dimensions for your PCB layout. Cross-reference the full part number with the latest product data sheet to confirm compliance with current JEDEC standards and RoHS directives before finalizing procurement.

Selection Notes

Select this component when interfacing circuits requiring HCT logic levels with a 4.5 V to 5.5 V power supply. The TSSOP6 package is suitable for space-constrained surface-mount designs. Consider the 29 ns maximum propagation delay for timing-critical applications. Verify that the input voltage levels align with the driving source to ensure proper logic threshold recognition within the specified operating conditions.

Part Context

This component belongs to the Nexperia 74HCT2G series of single-function gates. It shares functional similarities with other dual-buffer devices in the family but is distinguished by its specific HCT logic compatibility and TSSOP6 packaging. The device is designed for general-purpose digital applications where signal integrity and compact form factors are prioritized over automotive qualification or extended voltage ranges found in other series variants.

Replacement Considerations

The 74HC2G16GW serves as a logical alternative if CMOS input levels are acceptable instead of TTL levels. For automotive-grade requirements, verify availability of qualified equivalents such as the 74HCT2G16DC-Q100H. Ensure any substitute maintains the same pinout configuration and package type to facilitate direct replacement without PCB redesign.

FAQ

What is the difference between the 74HCT2G16 and 74HC2G16?

The primary difference lies in the input switching levels. The 74HCT2G16 utilizes TTL-compatible input thresholds, making it suitable for interfacing with 5V TTL logic, whereas the 74HC2G16 uses CMOS input thresholds.

Does the 74HCT2G16GWH have Schmitt trigger inputs?

No, the 74HCT2G16 does not feature Schmitt trigger inputs. It relies on standard CMOS input switching characteristics defined by the HCT logic family specifications.
